Title: RandyMarsh's DIY Pedal Mods (Two New Pedals In the Works)
Post by: randymarsh on November 16, 2008, 04:17:33 PM
Share ko lang :D Kakatamad kasi tuwing weekends eh. Hehehe.

Page 1 - SD-1 mod
Page 2 - CS-3 mod
Page 3 - GE-7 mod
Page 4 - Proco rat Clone - The Splat Rat
Page 5 - Ibanez TS808 Clone - El Grapadura
Page 6 - Marshall Bluesbreaker Clone -"YBMB"
Page 7 - Duncan Coffee Distortion
Page 7 - Zendrive Clone ni Aling Minda
Page 8 - Vox V847 Wah Mods
Page 9 - Vox Satchurator True Bypass Mod
Page 9 - Boss XT-2 Xtortion Mods
Page 10 - Boss MT-2 Metal Zone Mods
Page 11 - How to Mod Pedals
Page 11 - Boss CE-5 Wet/Vibrato Mod

Clarify ko lang din na hindi ako tumatanggap ng mods and I'm not planning to turn this into a business anytime soon. Masyadong malakas kumain ng oras ang pag mod ng pedal pero rewarding naman pag natapos na.  :-D

Ang maganda pa dito, by swapping components around pwede mo i-customize yung pedal to sound just the way you like it.

Bill of Materials
(http://farm4.static.flickr.com/3226/3034371658_f8494d339b.jpg)
1 x Boss SD-1 - poor SD one, fresh from the store ni-reyp na agad  :-D
3 x 0.1µF capacitor
2 x 1µF capacitor
1 x 620k resistor
1 x 2k2 resistor
1 x Burr Brown OPA2134PA IC
1 x IC socket

Capacitors and Resistors
(http://farm4.static.flickr.com/3036/3033532867_9388fd4d9a.jpg)
Kinausap ko yung nasa electronics shop at sabi niya mas ok for audio applications ang metal film capacitors and resistors. Sinubukan ko yung monolytic tsaka metal film capacitors, mas ok nga yung metal film IMO. Yung ceramic di ko na sinubukan. Sa resistor naman, metal film lang yung nabili ko.

Instructions
(http://farm4.static.flickr.com/3153/3034370926_83644d1cb9.jpg)
Replace C2, C3, and C8 to 0.1µF
Replace C7 and C10 to 1µF
Replace R2 to 620K
Replace R6 to a 2K2
Replace U1 to Burr Brown OPA2134PA + IC socket

(http://farm4.static.flickr.com/3047/3034369428_3b81749bcf.jpg)

Ginawa kong socketed yung U1 para kung trip ko lang ibalik uli sa JRC4558d sisiw lang.  :-D

Final Product
(http://farm4.static.flickr.com/3069/3033531045_364e72cab5.jpg)

Sayang hindi ko na-record yung stock SD-1 para sana may comparison. Pero sa mod na ito mas naging hi-gain yung pedal, luminis at medyo quieter and tunog niya.

sound clip! (http://www.upload-mp3.com/pfiles/33604/sd1.mp3)

0:00 - 0:07 - clean amp (lc15r)
0:07 - 0:27 - clean amp + modded sd-1 all knob 12 o' clock
0:27 - 0:38 - overdriven amp (lc15)
0:38 - 1:17 - overdriven amp + modded sd-1 all knob 12 o' clock

Cost
1 brand new sd-1 - $99.00
caps + resistors  - $10.00
OPA2134PA IC - $8.00

Total - $117.00 (Php 3600)

enjoy :D

Got myself a new drill and a few germanium diodes. Added a switch sa SD-1 kung saan nakalagay yung 1n34. Iupgrade ko din lahat ng resistors and caps ng metal film.

hehe. thanks dude :D lupit din ng ds-1 mod mo. malayong mas sarap sa tenga kesa sa keeley ultra mod. mag two years na rin sa akin yung orig keeley ds-1 pedal ko at masyadong ma-bass yung mod na yun. sinimulan ko na rin yung ds-1 mod ko based sa keeley ultra mod, medyo tinitimpla ko pa yung mga caps and resistor para sakto lang yung bass, mids and highs. post ko din dito yung mod na yun pag malapit na matapos. :D

Final modifications to the SD-1

Got myself some Texas Instruments RC4558P chips. Time to test the "stacked" opt amp mod on my SD-1.

(http://farm4.static.flickr.com/3188/3050115868_3d97ee255e.jpg)

Stacked OptAmp Installed (palit din lahat ng caps and resistors)
(http://farm4.static.flickr.com/3188/3049277465_a8f82b445f.jpg)

Mas cleaner sounding yung Burr Brown na opt amp kesa sa stacked TI RC4558s pero mas mataas ang gain ng stacked. After swapping capacitors and resistors, I'm very happy with the outcome.

Next Project .... Boss DS-1 and Boss CS-3 mods

nice clips sir. okay yan opa2134pa, transparent and low noise, chip is not that fast, so no problem running it with 9v. best yan kung gagamitin sa mga compressors and other clean pedals, although you have to make an adapter for it if you 'll fit it cs-2, cs-3. next up the 2134 is opa2132 and opa2107. theyre quite expensive, and we use 'em more on driving audiophile headphone amps or cd players because of its transparency and presence .

Natapos din sa wakas :D

(http://Boss CS-3 Mod)

Bill of Materials
Resistors (metal film type preferred)
1 x 470 ohms
1 x 100 ohms

Capacitors (metal film non-polar, poly or mylar type prefered)
2 x 0.47uF
4 x 1uF
1 x 2.2uF
1 x 47uF (Tantalum type)

Wires - just in case hindi magkasya yung cap sa PCB, especially for the 2.2uF capacitor.

ICs (optional)
Burr Brown OPA2134PA
PCB bread board
1 x 8 pin socket (4 per side)
1 x 8 pin socket (8 inline)

Instructions
Replace R5 to 470ohms
Replace R36 to 100ohms
Replace C1 and C2 to .47uF
Replace C4, C6, C17 and C14 to 1uF
Replace C13 to 2.2uF or (1.47uf, 1 x 1uF and .47uF in parralel, kung ayaw nyo na ma-bass)
Replace C3 to 47uF (tantalum)

Optional : Op Amp upgrade ala Monte Allum
2 x 4 pins to 1 x 8 pin converter.


Remove IC2 (NJM4558) and replace with 8 inline IC socket. Recommend ko na gumamit ng desoldering braid para mas madaling tanggalin yung IC and hindi masira.

Cut a square 10 x 10 hole sa pcb bread board. Gamit kong paa ng adaptor yung mga tira tirang wire galing sa resistor. Eto yung layout sa PCB para dun sa adaptor.

(http://i48.photobucket.com/albums/f221/silverarj/8pinconverter.gif)

Eto yung gawa ko. Ampanget pero pwede na :D

(http://farm4.static.flickr.com/3160/3052353898_d9bb9658a9.jpg)

Chip installed, mas mabright at mas mavolume yung TI4558 at JRC4558 op amps pero mas malinaw naman yung tunog ng nung Burr Brown chip.
(http://farm4.static.flickr.com/3041/3052351912_9017e90ef1.jpg)

Pinalitan ko din lahat ng resistors at capacitors, badtrip lang dahil maliliit na resistors ang ginamit nila sa CS3 pero ang laking improvement naman sa pagreduce ng noise sa pedal na ito.

Final Product
(http://farm4.static.flickr.com/3070/3052353104_552f015633.jpg)

Sound Clip!! (http://www.upload-mp3.com/pfiles/35152/cs3.mp3)
0:00-0:07 - guitar and amp
0:07-1:17 - CS 3 engaged all knobs set to 1 o' clock (compressor mode).
1:17-2:23 - CS 3 engaged, attack at min level, sustain at max level (limiter mode)

enjoy :D

I'll do the mod to the SD-1 here. I have to list the materials and check kung available ba dito. Baka close din mga stores 'coz fiesta eh. hehehe!   :-D Maybe I can't find the Burr Brown OPA2134PA IC here, but can I use the same OPA2134PA? 1/4 watt lang naman lahat ng resistor diba?

cool! yup 1/4 watt lang yung mga resistor. yung opa2134pa gawa ng burr brown. di ko alam kung may ibang manufacturer ng same chip, kung walang opa2134 hanap ka nalang ng ti4558 or isa pang jrc4558 then perform the stacked op amp mod :) you can also add a switch and wire an LED in series sa D5, it will boost the volume a little bit and add more clarity to the sound.

good luck bro. let us know kung magustuhan mo yung tunog after ng modification :)

oo doc. nasubikan ko na with the ds-1 and sd-1, may hiss pero tolerable. parang naglagay ka lang ng booster sa harapan ng distortion pedal. pansin ko nung nagsisimula palang ako mag-mod, pag todo yung sustain ang lakas ng hiss. after the modification maririnig mo lang yung hiss pag nilaksan mo yung amp. kaninang umaga, bago pumasok sa office nakapag gitara pa ako ng 30 minutes. ganda kasi ng tunog eh (or psychological effect lang siguro yun :D)

Balitaan mo na kami pag magawa mo na din. Sana mawala lalo ingay.

Badtrip kasi ako sa CS-3 ko sobrang hiss kahit naka-NS-2 pa ako may lumulusot pa din na ingay. Kaya yung akin for clean & slightly dirty tones lang talaga.  :-(

tingin ko wala na dun sa 4 na natitirang ceramic caps yung noise kundi nandun na sa nakacascade na op amp. 3 kasi yung jrc4558 dun at yung nasa output stage ang napalitan ko. try ko palitan yung dalawa ng opa2134 or ng ti4558 chips.

oks naman yung noise level ng cs3. same level lang din yung noise parang ds1 + booster pedal. nakatodo na yung sustain sa cs3 nun.

Interesting discovery para sa CS-3 Pwede i-convert yung CS-3 to a distortion pedal by removing IC4  :lol:

oo doc. tolerable maman eh. parang ingay lang ng naka single coil na strat or naka boost pedal. pero try ko palitan yung isa pang jrc4558 baka mas lalong mawala yung hum.

ano mod na natin cs3 mo?  :-D

$20 yung bili ko sa bcb30, display item kasi. :D

yeah puro boss pedals naman trip ko ngayon. this weekend baka ge7 or od3 ang bilhin ko para ma mod uli :D mas okto kasi dami akong pedals sa pinas na harsh ang tunog, tulad nung seymour duncan tweak fuzz. at least nagkakaidea na ako kung ano ang dapat gawin kung gusto kong i-improve yung tunog ng pedal.

Next DIY Mod Project - Boss GE-7

(http://farm4.static.flickr.com/3290/3063452886_bee06e2bb1.jpg)

Same process uli, upgrade ng caps and resistors. Tapos palit ulit ng LED ng keeley blue. Then finally change the three JRC022D op amps with TL072s at yung isang jrc2068 op amp with a 2 x 4 pin adapter and a burr brown chip.

Napansin ko sa GE-7, pag naka +15 lahat ng slider ng EQ, may noise ng kaunti, amplified pag sinamahan ng dirt pedal.

Nagbago din ang layout ng circuitry ng GE-7.

Almost complete, pero pwede na i-pang demo.  :mrgreen:

I call it the Boss GE-7 Hush mod

(http://farm4.static.flickr.com/3198/3066950148_335cdd10b1.jpg)

Gaya nga ng dati, upgrade caps and resistor. Pero ang major modification ng pedal na ito ay yung replacement ng apat na ICs (at syempre yung blue LED  :-D).

JRC022D -> TL072 - tatlo yung JRC022Ds sa bagong GE7, dati, based sa lumang specs, TL022 ang gamit ng boss. Siguro nagtitipid na naman.

IC4: JRC2068 -> Burr Brown OPA2134. Based sa lumang specs, low noise single amp ang gamit ng Boss GE7. Ngayon pinalitan nila ng Dual op amp JRC2068 which has a characteristic of 0.001% noise. Kaya palit ng Burr Brown na 0.000018% ang THD + noise properties. For this replacement, kelangan uli gumawa ng 2x4 to 1x8 socket adapter (see Boss CS3 mod on in this thread).

(http://farm4.static.flickr.com/3050/3066800024_91a13432d1.jpg)

As you can see, hindi ko pa napapalitan lahat ng caps and resistors (naubusan na ako ng caps napamalit  :-D) pero bumaba na ang noise level nito. Pansin ko nung stock pa siya, once na naka-up lahat ng sliders sa EQ may noise na akong naririnig. Ngayon natanggal na yung noise sa sliders.

I always wanted an EQ pedal and planned to order a modded one from analogman. Kaso ayokong maghintay, tulad dati nung umorder ako kay Keeley ng Boss DS Ultra and BD-2 Phat mod. I tried the behringer EQ pero never used it live kasi maingay pag may kasama nang dirt pedal. With the GE7 you can get dial in a "cocked wah" sound without a wah pedal and make the lo-fi guitar sound with a few adjustment of the sliders.

Sabado na naman! :D Wala munang pedal mods this week kundi diy clone naman. Sinubukan ko gumawa ng pedal based sa schematic ng proco rat mula sa mga tira tira kong parts.  Eto kinalabasan

The Splat Rat

(http://farm4.static.flickr.com/3082/3085378655_882d6bfbc4.jpg)
Too much gain kaya "splatty" ang tunog.  :-D Kasing laki lang din siya ng Mi-Audio pedals. I bought the enclosure sa jaycar electronics dito sa AU at parehong pareho sila ng m-audio, mukhang dun lang nilabinibili yung components.

(http://farm4.static.flickr.com/3100/3085379617_38a7eb22d5.jpg)
Breadboard lang :D Nilagyan ko ng dalawang DIL switch para sa clipping section kaya pwede mag set ng dalawang clipping modes na pwedeng piliin via mini spdt switch sa harap. ang options ay silicon diode, led, mosfet tsaka germanium diodes. sa ngayon ang favorite clipping modes ay yung led tsaka yung mosfet. ok din yung silicon, pag germanium diode naman ang clipping, ang laki ng bawas sa volume nung pedal at mas mataas yung gain.

(http://farm4.static.flickr.com/3008/3085377287_e0e5a80bfc.jpg)
Ang gamit kong opamp ay lm308. Ok din yung NE5534AP na chip, mas malinis ang tunog.

Yung knobs, same as rat, dirt, tone at volume. Dalawang switch, yung isa para sa clipping mode, yung isa booster mode. Siyempre true bypass and clear blue LED  :-D

Post by: randymarsh on December 06, 2008, 04:25:54 PM
thanks.  :-)

nagcheck uli ako at nakita ko na mali pala connection ko sa tone knob kaya naging "splatty" ang tunog. now using the germanium diodes as the clippers, this pedal sounds so sweet! :)
Title: Re: RandyMarsh's DIY Pedal Mods (Proco Rat Clone - page 4)
Post by: randymarsh on December 06, 2008, 05:29:40 PM
Isa pang demo uli using Germanium diode clipping and Mosfet clipping.  :-D

(http://farm4.static.flickr.com/3026/3086693916_fba09c6139.jpg)

I found some problems in the circuit kaya masyadong bassy yung pedal. Binalik ko uli yung LM308 and changed the clipping control panel  :-D instead na LED, germanium diode (OA91) ang gamitin.

thanks pala sa mga nag-iinquire sa splatRAT. nakakataba kayo ng puso :D however i have no plans of mass producing this pedal (as mention in my first post in this thread, though i'm decided to build three more for my friends at dun sa naunang nag-inquire for free, kung may spare time  :-D). it will be a violation of IPR kung i-mass produce ko and make profit of proco's design.

maraming salamat uli.  :-)

Malapit na matapos.  :-D Circuit is based on the Ibanez ts808 circuit with modifications to add more bass, better tone knob and gain knob range.

(http://farm4.static.flickr.com/3155/3099180720_ab6d644f57.jpg)

Features :

Clipping control panel - switch between GE, Silicon, LED and Mosfet clipping section
Clipping mode selector - switch between two clipping setting set in the control panel
Asymmetrical/Symmetrical switch- change clipping modes by removing or adding another diode in the clipping section
TS808 to TS9 switch - add more treble by switching to TS9
True Bypass
Hi grade components
Swappable IC - right now it's using a Texas Instrument RC4558 chip.

Malapit na matapos. I'm cleaning up the connections.

And this pedal has an owner already :D Will post clips/videos soon. Stay tuned. :)

Thanks Laur. :) Pinagtripan ko kagabi yung ts808 clone. Swapped a few more components to have more bass and more gain. It does have a good overdriven sound. Pero honestly, I'm not a tube screamer / SRV tone fanatic. Nai-compare ko din yung tunog sa mga videos na available sa youtube, no doubt, this baby is a certified tube screamer clone. Pero I love hard rock and heavy metal distortion sounds kaya for my next project, kahit may parts na ako, I'll be aborting my zen drive clone project for a DIY heavy metal pedal. :-D

Nakakareceive pa rin ako ng inquiries tungkol sa pedals. Again, ayokong gawing business to pero ang kukulit nyo. :-D Salamat sa inyo.

Ok, I'll be in Manila for one week, the first week of January . I'll be bringing with me 3 (three) brand new modded SD-1s for sale. I'll be buying the pedals here in Sydney sa Allan's Music (google nyo nalang) for $90 (Php 3000). Unahan nalang, pwede magpareserve.

Modifications will be
- Upgraded caps and resistors
- Symmetrical / Asymmetrical switch
- Op amp of choice (JRC4558, TI RC4558, Burr Brown OPA2134)

Modded SD-1, stock JRC4558 - Php 3300
Modded SD-1 with Burr Brown Chip - Php 3600
Modded SD-1 with TI RC4558 - Php 3400
Modded SD-1 with stacked TI RC4558 - Php 3500

Also, I'll be accepting pedal modifications (SD-1, CS-3, GE-7) sa while I'm in Manila pero for 5 forumites lang. The SD-1 mods will cost from 300-600 pesos, dipende kung anong chip ang gusto nyo. For the CS-3 and GE-7, I will post the prices later.

Again, first come first serve. Tatlong SD-1s lang and pedal mods. Yung magpapareserve sa pedal mods at bibili ng modded sd-1s, post nyo nalang names ninyo dito para ma-iprepare ko yung pedals and parts.

 :-)

After reading a thread about a pedal maker not able to deliver, napaisip ako. Kaya i-cloclose ko na yung offer ko. Pero dun sa pinadalhan ko ng reply, tuloy pa rin tayo :) Dun sa mga nagpapabili ng parts/pedals, sorry mga bro, pero ayokong masira pangalan ko kung magkaroon man ng aberya or problema. I am currently employed as a team lead in the biggest airline here in AU at ayokong magkaproblema dahil for a couple of hundred or thousand pesos.

Hindi na uli ako mag-eentertain ng PMs ng gustong bumili ng pedals and gustong magpa-mod. Pero dun sa mga nauna na at pinadalhan ko ng reply (kilala nyo na kung sino kayo) at mga barkada ko, tuloy pa din tayo.  :-)

Another boring weekend.  :-D

Presenting the "YBMB."

It's a Marshall Bluesbreaker clone with modifications to add more bass and a meatier crunch.

(http://farm4.static.flickr.com/3250/3123198925_8700c08155.jpg)

A friend requested me to build this pedal, part by part clone of a marshall blues breaker but I decided to experiment with different resistor and capacitor values. This also features two types of clippers which is selectable vai two dpdt switches.

Short Youtube Demo (http://au.youtube.com/watch?v=qH32ZxrAAUs)

na back order yung germanium transistors at silver mica caps ko. baka next year na dumating yun dahil sa holiday seasons.

natapos na rin yung dual footswitch, heavy distortion pedal ko. palit LEDS nalang kulang dahil masyado maliit yung 3mms.

Para sa mga metal heads, eto para sa inyo.

Duncan Coffee Distortion

(http://farm4.static.flickr.com/3113/3130799076_3c7d7e726c.jpg)

It's based on Keeley article on FET distortion. I beefed it up by adding another gain stage. I'm using a 2n5458, a MP102 and two J201s transistors. Also a TL071 IC for the clean boost circuit. It's a two in one boost/distortion pedal. You can use the boost circuit independent of the distortion circuit. It's Powered by a single 9v battery.

Merry Christmas everyone  :-)

Para sa mga metal heads, eto para sa inyo.

Duncan Coffee Distortion

(http://farm4.static.flickr.com/3113/3130799076_3c7d7e726c.jpg)

It's based on Keeley article on FET distortion. I beefed it up by adding another gain stage. I'm using a 2n5458, a MP102 and two J201s transistors. Also a TL071 IC for the clean boost circuit. It's a two in one boost/distortion pedal. You can use the boost circuit independent of the distortion circuit. It's Powered by a single 9v battery.

thanks sa mga nagreply.  :-)

here's another pedal. i call it...

Aling Minda's Zen Cocodrive SG

It's a zendrive clone. And the most troublesome pedal i built. Madali lang yung circuit pero it took me two days to troubleshoot. Sira na pala yung volume pot. I manage to damage it while drilling some holes on the aluminum casing, kaya nadelay yung three in one na pedal ko.

(http://farm4.static.flickr.com/3288/3140154445_8c1df522de.jpg)

crappy artwork. it's a hologram cover of a famous cartoon movie.
(http://farm4.static.flickr.com/3291/3141256932_66277a32e5.jpg)

I modified the circuit. I added a SG switch for the clipping section. Pwedeng pumili between germanium diodes or schottkys. May slight scoop ang tunog ng germaniums and gets really nasty at full gain. Slightly brighter naman ang schottkys at oks pag full gain. I'm also using an analog device AD712NJ op amp.

(http://farm4.static.flickr.com/3292/3140977470_3ca1cd98ea.jpg)

Clips!! Not sure kung may chirp yung videos. I'm not a robben ford fan kasi at di ako familiar dun sa chirp na tunog. I hope meron sa mga demo ko.

Ser gusto ko yung sound nung clone nyo Pwede bang mag pagawa nyan ahihihi and how much po ser... one more question kaw ba si arjin ng yupangco forum nun nag EEB kila ten???..

Yes i'm arjin at ako nga yung umattend kila ten years ago.  :-) Sorry dude, I'm building these pedals for myself. Masyado kasi malakas kumain ng oras eh. You can get jmorrero's D-Zound or kramtone's ZDC. IMO, pareho lang naman din lang ang tunog nun kung same yung circuit at components na gamit.

Or I can point you to the schematics if you like. It cost me about 50 AU dollars (Php 1500) to build it. Ang pinakamahal na component ay yung 3dpt footswitch. It's a pretty simple build. Ang pinaka ayoko lang yung pag butas ng aluminum casing.

On a different note. Here's another demo of the Duncan Coffee Distortion. My wife bought me a new DVR.  :-D

cool! thanks for the videos. :-D sarap mag experiment kung marami ka ngang components. lupit din yung black dzound na gawa mo. :)

i don't have an orig zendrive to compare my pedal with. kung meron ako niyan then i will never waste my time building a clone. and i read na meron kang orig kaya mas credible yung dzound mo kesa clone ko. there's a missing cap in the jetter schematics, ngayon ko lang napansin :D

i love high gain pedals and the zendrive is not my cup of tea. kabadtrip din maghanap ng opamp at germanium diodes, at yung nasayang na araw sa pagtroubleshoot nung pedal, kaya i'm not that excited with my zendrive clone hence the crappy name "aling minda's cocodrive". i'm just happy it turned out ok. :-D

cheers sa black d'zound  :-)

Part two of the modded Vox wah series.

i've added a new knob called "crackle ok" and more settings on the multi wah knob. I've replaced the color changing LED to a regular orange one. I found out that the LED is adding noise to the wah effect. And finally a switch to enable the Super Hard On pre boost.

-True bypass switch
-Vocal like sweep
-Multiwah - 11 wah modes and a volume pedal mode accessible via selector knob.
-SHO (Super Hard On) pre boost circuit with switch and "crackle ok" knob.
-Orange LED

Question.. with the Vox V847 mods that you did, does the pedal handle high gain better now? Ang dami ko kasing nababasang reviews na hindi maganda ang tunog nitong Vox wah with high gain. :-)

Good question. i haven't tried it actually with a distortion pedal. Pero nasubukan ko siya gamit yung distortion ng amp mukhang ok naman. Will try it with a distortion pedal tomorrow.

I did have the same problem before with a boss foot wah, maganda sa clean pero panget sa distortion. I also have a crybaby and a morley bad horsie, dun wala akong complaints.

The Vox wah sounds ok with distortion pero not as good as bad horsie wah. The problem with the vox wah is the heel down sound, medyo bawas ang gain. Parang may volume swell effect, yung heel down ang mahina ang volume. Kaya hindi convincing yung wah effect sa distortion lalo na if you are going to play wah licks ala shash or kirk hammett. Pero oks siya sa cocked wah ala blues saraceno or zakk wylde.

Aling Minda's Zen Cocodrive SG

It's a zendrive clone. And the most troublesome pedal i built. Madali lang yung circuit pero it took me two days to troubleshoot. Sira na pala yung volume pot. I manage to damage it while drilling some holes on the aluminum casing, kaya nadelay yung three in one na pedal ko.

I modified the circuit. I added a SG switch for the clipping section. Pwedeng pumili between germanium diodes or schottkys. May slight scoop ang tunog ng germaniums and gets really nasty at full gain. Slightly brighter naman ang schottkys at oks pag full gain. I'm also using an analog device AD712NJ op amp.

no compressor sir. it's tube amp compression from my laney lc15r. single channel lang siya i set my gain at 8 o' clock and yet it distorts a little when you pick hard. very typical sound of a laney lc amp. add mo pa yung high output jb model bridge pickup sa guitar ko.  :-D

I've been fascinating with pedal modifications and boutique pedals these past few days because of the Vox Satchurator mod... Hehe.

Kasi nung makita ko ung Satchurator sa stores and ung Jemini, I thought they are somehow "perfect" kasi anlulupit nung mga signature namesakes nila. Tapos un pala kaya pa talaga iimprove.

Gaganda ng gawa niyo sir. More power! :-D

Thanks. Yan kasi problem ng mass production. Companies will try to keep the costs down as much sa possible para mas malaki ang profit. For example yung 3pdt footswitch costs $10 pero instead ginamitan nila ng switching components for half the cost. And sometimes they will use low grade components para lalong makatipid sacrificing the pedal's tone and floor noise level.

Last week when I got the Satchurator, this caught my attention.

(http://farm4.static.flickr.com/3078/3205553501_bb0ea03d68.jpg)

It told myself, after a week, kung nandito pa ito, kunin ko na ito.  :-D

Medyo deceiving yung name "Xtortion". Akala ko din nung una parang metal zone. It's somewhat in the territory of the metal zone and the ds-1, tweakable with the "contour" knob. Yung "punch" knob naman is like a frequency notch, parang cocked wah effect (ala zakk wylde). Medyo noisy itong pedal na ito dahil it uses 3 mitsubishi general purpose opamps and a lot of 1uF electrolytic caps. I experimented with the opamps, I tried OPA2134 , TI RC4558s, tl072s and AD721s. The opa2134 overloads the distortion circuit, ok naman tl072s pero pag dalawa na silang pinalitan, nagfefeedback na. The RC4558s are just right. Laki din ng difference sa tone at floor noise levels. :)

Added two switches (umiiral na naman pagiging programmer ko  :-D)  the first switch is like a frequency selector for the "punch" knob. I was able to approximately dial in Dimebag's CBFH tone with this switch in conjunction with the contour knob, pero konting tweak pa sa tone stack. The second switch disables the "punch" circuit, parang OD mode. Might put a J201 FET here. Still a lot of work needs to be done with this pedal.

Will post my mods here pag natapos ko na. :)

kaya i added a switch to bypass the punch circuit with makes this pedal sound boxy. i loose a lot of gain by doing that, kaya try ko mag-add ng biased j201 or an mpf102 para maibalik uli yung pagka distortion ng pedal :)

I don't have the schematic on me at the moment (as in on my person right now)...

But if you need more gain, try tweaking the gain stages that come before or after the punch circuit and raise the gain by adjusting the Rf/Ri ratio...normally by increasing the value of the feedback resistor of the gain stage.

This way you won't need to add an additional FET.

I'll be more specific when I get to my computer :-D.

But thanks for that suggestion of disabling the punch circuit. That should be a starting point for me.

FWIW.

Thanks for the tip. I'm using a dpdt switch to bypass the punch circuit. I don't know if I have space in the pedal to replace it with a 3pdt for the resistor swap in the first feedback loop. Or probably I could put another switch! :D The more the marrier! Hehe.

Got it. The easiest and most versatile way to have more gain available is to replace vr1 with something higher. From 50k stock, replace to 100k or even 250k. But maybe you should try 100k first. This will raise the available gain of the pedal prior to the clip stage para "distortion" pa din sya, even when the punch circuit is bypassed.

Oops before I forget. VR1 is the distortion potentiometer :-D.

Maybe together we'll crack this pedal.

cool! i'll try this out tonight. pwede nga i-bypass nalang yung punch, tapos replace ICs 1 and 2 with TI rc4558s. Medyo increased na yung gain pag nagpalit ng opamp kaya increasing the value of the distortion pot seems enough and makes it more organic sounding.  :-) replacing the 1uF caps with mkt caps reduces the noise.

another trick i did is to change the capacitor on c23. this moves the "punch" frequency. with bigger value (around 150nF) parang heel ng wah ang tunog and with lower value (39nF) parang tip naman ng wah. i placed a switch here para pwede ko ibalik sa stock or to another cap that i like.

I've compared the stock GE-7 with your modded GE-7 na. Got to gig with the modded pedal last night. :lol: Works as expected. Nice fat boost (if thats what you're using it for) for solos.

At gig levels, and the way i set it, its just like a regular GE-7. Last night i used my Edwards e-lp-98lts with skatterbrane A2's into a keeley rat then GE-7 then some small 1x12 laney (kung anong model man yung nasa route 196). Like I said, it worked just like its supposed to, just like a regular GE-7. Its an EQ pedal anyway. No "it made me sound 10x more musical" miracles here. :lol: Plus, the way i set it isn't extreme at all (400=+3, 800=+5, 1.6k=+5, 3.2k=+3, the rest at 0, level anywhere between 0 to 5 depending on how the amp reacts to the boosted frequencies) so yung gains of using higher quality components isn't that obvious. I use it massage the right frequencies into place as opposed to hammering them into submission.

Those gains I only saw this morning. I made 3 vids. I used a Burny lc-70rr with SD '59/JB pups. I kept it on the JB (the noisier of the 2 pups) the whole time and didn't play at all. The guitar was just there to introduce regular guitar electronic noise. The amp is my old Marshall 8040 on the clean channel cranked up to 8 (which is why i couldn't do any actual playing; maaga pa e). Everything is connected with cables I made myself (klotz cables and neutrik connectors). I tested the EQs 2 bands at a time, all the way up (which is the wrong way to use EQ for guitar). Level at 0.

So, here are my err... findings:
1) 6.4k and 3.2k - halos identical. both pedals sounded hissy. which is to be expected. you're boosting white noise frequencies from the guitar electonics and cables after all. medyo finer grained lang yung hiss from the modded pedal pero hissy pa din :lol:
2) 1.6k and 800 - here you'll start hearing the difference na. at these frequencies (where most guitar's "meat" is and the frequencies normally boosted for solo work to cut through a dense mix), the modded box was considerably more quiet here.
3) 400, 200 and 100 - again, you'll immediately notice how much more quiet the modded pedal is at these frequencies. in fact, at these frequencies, yung hiss you hear from the stock pedal is almost non existent on the modded one.

you can actually hear these differences dun sa vids i made with my crappy digicam and its crappy built in mic. :lol:

so yun. arjin, good on ya mate. :lol: i'm keeping this. :-D i'll post the vids in a bit or send them to you.

I gotta close the case on this xt-2 xtortion mod.

here's what i've done so far.

replace all 1uF electrolytic caps with 1uF MKT caps (reduces noise)
except for c10, replace with 33nF capacitor (reduces the muddiness of this pedal)
replace r23 with 100 ohm resistor (increases distortion)
replace c16 cap with 33nf (makes the contour more usable before the 11 o' clock range)

video:
http://au.youtube.com/watch?v=07jplUUSiyE


optional
replace IC1 and IC3 with TI RC4558 op amp. the mitsubishi opamp sounds harsh to me. it also increases the gain of the pedal.
replace IC2 with Burr Brown OPA2134 op amp. Reduces the noise coming from the punch circuit and has better tonal characteristics than the stock mitsubishi opamp.
replace clipping LED1 with a germanium diode.
add switch between r20 and r21 - bypass punch circuit
change c23, this is for the punch knob. higher value gives it a bassy, wah weel type sound. lower values gives it a more nasal wah sound.

next pedal inline for modding  :-D

it's good sounding but not that great. i mean, it does have a unique sound but it can be achieved with a DS-1 plus an EQ pedal or a wah. I managed to take away the muddy tone, but then it starts to sound more like a ds-1.

How to Mod a Pedal

At some point this thread will have to end.

I'm not a tone connoisseur, i don't have the funds to buy top of the line amps/guitars. Unfortunately, I don't even have a band right now and my playing skills is not up to par. But I want to share to everyone what I've learned in the past few months of modding and building pedals. Most of you may not know me and being almost a noob here, my intention is just to share information.

My Modded Pedals
(http://farm4.static.flickr.com/3400/3225048358_d3dc1e83cf.jpg)

Before You Mod a Pedal

There are lots of way to improve your tone before resorting to modded or boutique pedals. Here are some tidbits that I learned over the years.

- Guitar. Check your guitar first. Send it to a luthier for a good ol' general setup. You may want to upgrade your no-name (or manufacturer stock) pickups to decent branded ones. DiMarzio, Seymour Duncans, Bare Knuckles, Elegee, etc, will do just fine. You may also want to disconnect the tone knob from your guitar's circuit (or you can replace the tone knob pot with a "no load" pot).
- Strings and Picks. Make sure that the strings loaded in your guitar are still ok. Replace them if necessary. There's a trick that I do when I was still in high school, I would get a pot and boil water, dip in the wound strings for a minute and wipe it with dry cloth. You may want to use heavier guage strings. Picks do affect your tone. I use 1.14mm Dunlop tortex picks for years. It never failed me.
- Cables. It's probably the cheapest and most effective upgrade. For years I've been using the cheap cable that came with my guitar. For 500 pesos (I think) you can buy Klotz cable which is way much better the more common, no name cables. Also the shorter the cable is, the better. I use Fender Tone Master Instrument cables, and IMO they are the best cables out there (that my wallet can afford).
- Pedals and Pedal Board. I have a few dozen of pedals but I don't have a working pedal board. I noticed when you start chaining two or more pedals in series you will loose some clarity in your guitar's tone (especially with pedals that uses input buffers). That's why when I jam with friends or play with my old band I'd bring only one pedal (and sometimes a wah pedal when i'm not lazy). There are times that I don't even bring a pedal with me. I'll just use the amp's distortion and back off the guitar's volume knob to dial in clean tones. (A EQ pedal can also improve your overall tone).
- Amp. There are lot's of decent solid state and cheap tube amp out in the market. Even though some will swear on their expensive amp, for me it's not a big deal. It's not like you will be playing infront of Eric Johnson or your d*ck is at stake when you have bad tone. Just make sure that you don't play with a blown speaker and dial in some mids.
- ETC. I prefer to stay away from unnecessary devices. The shorter the signal path is, the clearer tone your guitar will have.
- Fingers. Enough said.

Tone is also subjective. It differs for person to person. Modding your pedal does not always equate to a better tone. I've seen many mods on youtube that sounds nasty for my taste. You may also want to try backing down the gain a little bit, in which at loud settings may sound very effective (Thanks Nathan!).

Tools

The things that you will need when performing modifications.

-Guitar
-Amp
-Guitar Cables
-Soldering Iron and Lead
-Resistors and Capacitors
-Jumper Cables
-Screw Driver
-Scissors
-Multimeter (optional)
-Audio probe - http://www.diystompboxes.com/pedals/debug.html
-Pedal Schematics or Pedal Mod guides
-Electrical tape

I bought this device (I forgot the name of this gizmo, it's the black device with a big Omega character) where you can hook it up to your circuit and change the value of the resistor with a turn of a dial. I also made a "dial in a capacitor value" device from 12 capacitors with different values, a pcb and a 12 position rotary switch (the device with lots of orange wires). The audio probe is useful for troubleshooting your pedal (there might be some instances that no sound will come out when you test it).

I buy capacitors and resistors in packs. It's way much cheaper and time saver to buy in bulk (especially if you are planning to mod a couple of pedals).

Basic References

You must learn how to read capacitor and resistor values before proceeding. Just google it and you'll find tons of resources on the internet. Here are some

Resistor Values - http://www.dannyg.com/examples/res2/resistor.htm
Capacitor Values - http://www.kpsec.freeuk.com/components/capac.htm

Basic Tone Mods

Most big manufacturers will use cheap components. That's why before I mod my pedal, I will try to replace all capacitors with MKTs, mylars or silver micas. You can also further reduce the pedal's floor noise by replacing those nasty 1uF polarized electrolytic capacitors with MKTs or tantalums. When I performed my first pedal mod, I tried to replace the 100nF and 1uF caps with precise metal film caps. It a little bit pricey (ranging from $2 to $10 each) but they do sound good (you will have problems squeezing them in your pedal's confined space).

Huge Yellow Cap

More Yellow Boxed Caps
(http://farm4.static.flickr.com/3188/3049277465_a8f82b445f.jpg)
I love modding dirt pedals because with minimal component change, you can immediately notice the difference when you test it. The first thing to look for are the high pass and low pass filters in the pedal's schematics. You can also calculate what frequencies to attenuate and what component values to use. Refer to the references below.

High Pass Filter - http://en.wikipedia.org/wiki/High-pass_filter
Low Pass Filter - http://en.wikipedia.org/wiki/Low-pass_filter

But I'm too lazy to perform calculations that's why I do it by ear. By using my DIY "dial in a capacitor" and my "dial in a resistor" (forgotten the product's name) devices, I would remove a capacitor and a resistor installed on the pedal's PCB, replace it with the dial device using the stock values. Then I'll connect the pedal to a guitar and amp (with guitar cables or with an audio probe), point all knobs on the pedal to 12 o clock and test the tones by ear. Choose your prefered tone by playing a few power chords and by incrementing/decrementing the values of the capacitor and resistor.

Here's an example using a Boss DS-1 and Boss MT-2 Metal Zone schematics (By the way I've done these mods to my pedals).

DS-1 - http://www.godiksennet.com/images/sch/DS1PG2.jpg
MT-2 - http://www.godiksennet.com/images/sch/mt2-06.jpg

Note: I'll be using the schematics of a Boss DS-1 and MT-2 for most of my examples.

For the Boss DS-1, I replaced C3 (stock value 47nF) to 39nF. With this small change, I was able to add more mids. I also made this change to my Vox Satchurator, now it has more mids that before (and now it sounds better than my DS-1).

For the Boss MT-2, I replaced C29 (stock value 33nF) to 100nF. With this change, i was able to add more bass to my pedal.

You can experiment with different resistor and capacitor values on the high/low pass filter using the schematics as your guide. It's also a good idea to take note of the changes that you have made, just in case you want to revert back to the original/modded values.

You can also change the caps and resistors connected to the tone knob as you like.

The basic rule is (depending if its a high or low pass filter)

- low value capacitors are used to increase/decrease higher frequencies
- high value capacitors are used to boost/cut lower frequencies

Also be aware that some capacitor types have polarity. I remember replacing an electrolytic cap with a tantalum with the polarity reversed. It produced weird sounds on my pedal and it took me days to troubleshoot the pedal.

Clipping Circuit

To locate the clipping section of a dirt pedal, all you need to locate are the diodes connected in parallel (Metal Zone - D4 and D3, DS-1 - D4 and D5). You can experiment with different components (LED, germaniums, mosfet) for the clipping circuit. You can also add another diode in series to one of the clipping diodes for asymetrical clipping. You can also increase the distortion/gain of a pedal by locating the resistor and capacitor connected in parallel with the clipping diodes (Metal Zone R13 and C23) or in series with the distortion knob (DS-1 R13 and C8). Increasing the values of the resistor in this section increases the pedal's distortion. The capacitor dicates the range of the frequency that will be clipped. Be sure to test the distortion knob's range before soldering your prefered components. Experiment.

Switches, True By Pass

It's an advantage if you can perform a true bypass mod on pedal. Unfortunately this mod is difficult to execute on Boss pedals. If you are a true bypass snob, you can rehouse your pedal and add a 3pdt heavy footswitch. Trace the pedal's input. Chances are, the first or second transistor in the circuit that you will encounter (DS-1 - Q6) will be the input gate.

Also with a help of a drill and installing some mini SPDT or DPDT switches to your mods, you can have more mod options at your finger tips. For example, on the Boss MT-2, using a DPDT switch, you can reinstall the caps C35 and C25 to the switch and wire them back to the PCB. You can disable these two caps with a flick of the switch, thus removing the harshness of the pedal. By flicking this switch again activates the caps as they were stock, retaining the factory default, hissy sound of the Metal Zone.

My Modded MT-2 and XT-2. I think it needs another switch.

Op Amp Upgrades

You can experiment with different opamps on your pedal. From costly Burr Brown chips to the famous JRC4558 chips. You don't have to replace the opamp unless, whatever capacitors or resistors you replace on the board, the pedal still sounds harsh or noisy. I tried replacing the stock JRC4558s on the Metal Zone using Burr Brown OPA2134 but it only increased the distortion of the pedal causing my other mods to fail. However, replacing the Mitsubishi M5128 chip in my DS-1 with an OPA2134 did remove the harshness of the pedal. Replacing an 8SIP chip with an 8DIP will require a chip adapter. Using an 8DIP socket and some wires, you can build your own chip adapter.

(http://farm4.static.flickr.com/3094/3207346169_07c30f819b.jpg)

Always make sure that the layout of the pins are correct and does not short with the other pins. Always refer to the chip's datasheet that can be downloaded from the manufacturer's website. Also do not install an opamp in reverse orientation because this may destroy the chip. I manage to burn a $7 Burr Brown chip and a $10 AD712 chip by placing it in reverse.

You can also check this reference from Texas Instruments when choosing a substitute opamp.

You can also modify the voltage that flows to the FET amplifier or input of an op amp. By doing this mod,you can clean up or add a little more distortion to your pedal. This is by changing the resistor value connected to the source of the FET Transistor (DS-1, R9) and/or the reference voltage that flows to the gate of the FET by changing the resistor that's connected to transistor's gate (DS-1, R6). On my DS-1, I increased R9 a little bit (to 100 ohms) to bias the gate to 4.2 volts, removing a little bit of distortion in the input amplifier stage. The same principle applies to op amps. By changing the reference voltage, you can have a cleaner or a distorted output from the op amp.

You can also increase/decrease distortion by changing value of the feedback resistor connected to the op amp.

Here's a good reference for op amps - http://williamson-labs.com/480_opam.htm

Closing Remarks :)

There you go folks. When performing mods it's important to take short breaks in between, especially when testing your modded pedal. Sometimes I'll test the pedal the day after. This way I'll now that my hearing has not been impaired and my thoughts not clouded by the fumes of the soldering lead. It's a lengthy post but I hope you'll benefit from this. Good luck with your pedals.

you're welcome :) yeah, i'll be still modding pedals pero i'm not going detail my mods here unless someone wants it. i'm still hunting for a jemini pedal.  :-D

:) there are some guidelines online pero pedal specific.

sir, natrace mo na ung satchurator??

yep. the main distortion circuit is very similar to a japan made ds-1 (binabawi ko yung post ko dati na hindi siya similar sa ds-1  :-D). i have to say it's a modded ds-1. they changed the switching, added the "more" circuit and "pad" switch and added additional components and a couple of 0 ohm smd resistor to caumoflage the ds-1 inside. it also uses, i think, a burr brown op amp chip. could be that's the reason why sounds cleaner and a little less harsh that the taiwan ds-1 equipped with m5128s.

ayos, sana may subject akong ganito, hindi ako magcucut non  :-)

i remember having EE and ECE classes in college with these topics. school subjects can be really boring until you can find ways of applying the theories to real life, lalo na sa paggigitara. :D

di pa ako nakakagamit ng jmp-1. pero nagkaroon na ako dati ng digitech gsp 2101. you can get the schematics of the marshall jmp-1 here

http://www.drtube.com/schematics/marshall/jmp1-61-04.pdf

if your jmp-1 is more than 10 years old and constantly using it, probably you can replace the caps to make it sound like new again as they will loose capacitance with age and with the heat produced by tubes. i'd stay far away from the tube area as you can get electrocuted.

Boss CE-5 Wet/Vibrato Mod (Very Easy!)

I call this "the Wet mod" because with this mod you can remove the dry signal from the effect out in output A. The result is the wet vibrato signal. You can get the same effect by plugging an extra guitar cable in output B and using output A as your main signal output.

All you need is a drill, wires and a SPST or SPDT switch.

Connect wires to the ring and sleeve connector of output B plug and the other end of the wires to a switch. See image below.

With the switch mounted
(http://farm4.static.flickr.com/3366/3241670079_d653c75df0.jpg)

With this mod, I can switch between stock chorus or vibrato modes. No tone mods for this pedal because the components are surface mounted (for versions CE-5a).

Enjoy.  :-)

Post by: scuttlebutter on February 02, 2009, 10:33:58 PM
Malapit na matapos.  :-D Circuit is based on the Ibanez ts808 circuit with modifications to add more bass, better tone knob and gain knob range.

(http://farm4.static.flickr.com/3155/3099180720_ab6d644f57.jpg)

Features :

Clipping control panel - switch between GE, Silicon, LED and Mosfet clipping section
Clipping mode selector - switch between two clipping setting set in the control panel
Asymmetrical/Symmetrical switch- change clipping modes by removing or adding another diode in the clipping section
TS808 to TS9 switch - add more treble by switching to TS9
True Bypass
Hi grade components
Swappable IC - right now it's using a Texas Instrument RC4558 chip.

Malapit na matapos. I'm cleaning up the connections.

And this pedal has an owner already :D Will post clips/videos soon. Stay tuned. :)

Hi Arjin! Thanks so much for bringing El Grapadura into my life! I absolutely love it!
As promised, here is my review...

Product: El Grapadura
Price Paid: UNKNOWN
Submitted 02/02/2009 at 10:33pm by Scuttlebutter


Ease of Use: 11
It’s got 3 knobs – Volume, Tone, & Drive.

It also has 3 toggle switches –
The first toggle switch lets you choose between Germanium & MOSFET diodes.
The second toggle switch lets you choose between TS808 & TS9.
The third toggle switch lets you choose between Asymmetrical & Symmetrical clippings.

There is a control panel inside that can give you a Silicon/LED option on the first toggle.

Sound: 11
This pedal delivers the holy trinity of overdrive tones: sweet, warm, and smooth. The biggest challenge here is to find a bad sound. This pedal has none! Great job, Arjin!  :-)

The Germanium is very juicy while the MOSFET gives a really nice big singing boost! The TS9 mode gives a bit of a brighter tone compared to the TS808 mode. Symmetrical clipping is silky smooth while Asymmetrical clipping adds a bit of grit. Whichever setting you choose, El Grapadura will give you great tone!

The pedal has a good amount of volume! Unity volume on Germanium mode is around 10:30 while unity volume on MOSFET mode is about 9 o'clock. The tone knob is very responsive. The Drive knob is very generous.

I did 2 tests that I feel every TS and TS-type overdrive pedal should pass. The first test is for clones, which is an A/B with a real Ibanez TS. The second test is a play-along with an SRV jam track of the song Tightrope.

For the A/B test with an Ibanez TS808 Reissue, I was able to replicate the TS808 tone with toggles on Germanium/TS808/Asymmetrical. I haven’t tried bringing out the Silicon/LED option but I’m so happy with the current diode choices that I don’t think I ever will. The Grapadura not only matched the tone of the real thing, but surpassed the real thing’s versatility. So as far as the A/B test is concerned, El Grapadura passes with flying colors!

Stevie’s tone & playing in Tightrope is simply amazing. For the Tightrope test, well, I’ll be the first to admit, this is probably the most unfair test of all, for both the pedal and the guitar player. But the Grapadura did a pretty good job. It’s hard to duplicate Stevie’s tone and my playing certainly isn’t spot on, but with my strat & Blues Junior amp, the vibe & mojo are definitely there. The Grapadura certainly gets you in Tightrope and Texas Flood territory. I totally love this pedal. I wouldn’t trade it for a real Ibanez TS!

Reliability: 11
This thing is extremely well-built. I doubt this will ever break.

Customer Support: 11
Arjin is one of the nicest guys I know and I’m sure this will never be an issue should anything happen to the pedal.

Overall Rating: 11
Does the Grapadura give true TS tone? Yes, it does! That plus more! It totally rocks! But even with its versatility, it is still just an overdrive pedal. But what is does, it does really well. This pedal will excel in any type of music that calls for an overdriven guitar tone.

If it were lost or stolen, I wouldn’t hesitate to ask Arjin to build me another one!  :wink:

I’ve been playing guitar for quite a number of years now and I’ve played some really nice pedals. El Grapadura is up there with the big boys. And it makes me really proud that a friend of mine built this thing from scratch.

Thanks Arjin!  :-)

The Continuum Transfunctioner contains two different overdrive circuits, both "true bypass"-able. the right side of the pedal has more gain than the left side. with a flick of a switch you can reverse the order of the overdrives. each overdrive circuit also have a "boost mode" switch. with these options you can have two boost circuits, two overdrive circuits or an overdrive and boost circuit in one pedal.  :-D

The Bad-Ass Gravity Pump is a monster distortion pedal. The left side of the pedal contains two distortion circuits while right side is the boost circuit. With almost same features of the Continuum Transfunctioner but with more gain.

hope you can help me with this one, pakipost na lang..

i've tested the sd9's schematics using ltspice. yung tone section niya is big muff inspired, kaya tama ka na treble boost/cut ang function ng tone knob. pwede mo idecrease yung tone knob to B10k tsaka increase mo yung value R12 ng to 10k or 15k para medyo flat ang EQ ng tone knob mo at 12 o clock. hindi ko tested ito pero yan ang pinapakita sa akin ng graph.

hope this helps.  :-)

hmm, will try this one..

tnx for the help! :-D

this . thread . must . never . die      :-D
 
 
Here is my long overdue review of RandyMarsh's DIY creation - YBMB (short for "You're Breaking My Balls")
 
Brief background:
A couple of months back I was considering incorporating a low-gain OD pedal into my setup as an always-on pedal. The usual pedal buzzwords apply -- "touch sensitive", "dynamic", "amp-like", "cleans up nicely", etc. The usual suspects that were shortlisted were the likes of the Barber LTD and Gaspedals Carb OD. Then I stumbled upon clips of the CMATMODS Buttah, which according to one other forum that I frequent, is based off a Marshall Bluesbreaker OD pedal (the original one and not the current BB-2). I really loved the clips of the CMATMODS Buttah and immediately thought of that tone as something that I could use for my setup. Then, I also stumbled upon the knowledge that the AnalogMan KOT is essentially 2 identical Marshall BluesBreaker circuits in a single housing, with a some mods and upgraded components. Naturally, more GAS set in and curiosity about the BluesBreaker circuit got the better of me, hence I present to you guys the YBMB pedal by PhilMusic's very own, RandyMarsh.

(http://memimage.cardomain.com/ride_images/3/1009/3001/27521500033_large.jpg)
 
Build details:
The YBMB is clad in a tastefully and accurately applied one-piece decal (a window decal, I presume), which from afar actually looks as if it's a handpainted pedal. The control labels are sharpied on but thankfully, RandyMarsh's penmanship is helluva lot more legible than my chicken-scratch handwriting. A blinding blue LED was used for the indicator, which to be honest, in use in a dim room, can get a bit irritating especially if I'm trying to see the position of the two toggle switches beside it...it does look cool though from afar. There are a total of 4 knobs and 2 2-way switches (more on these controls below). The D/C input of the pedal is on the north-side as specifically requested from RandyMarsh (I personally hate pedals with the D/C input on the side of the pedal, but I do understand that most builders do this to have a cleaner wiring layout, i.e. no flying lead from the north side of the pedal going to the bypass switch).
 
Out of curiosity (and this is something I do with all pedals that I own), I opened up the YBMB to see the insides in all its glory, and what I saw was a shocker. The YBMB's guts reveal an extrememly tight build. I was astonished as to how RandyMarsh was able to cram all of these components in an MXR-sized box! The build was in fact so tight that the circuit board was not laying down as it is with most pedals, but was actually standing on its side over at the south side of the pedal, where a battery would usually be placed.
 
In terms of overall build, it's still an obvious DIY job, but one can clearly see the attention to detail, tight tolerances and the quality of circuitry and clean soldering.
 
Before I forget, the inside of the bottom plate was signed by Mr. RandyMarsh, alongside a sticker of a wizard. I'm not sure if the sticker was meant as a reference to his electronics wizardry (I wouldn't be surpised if it was).  :)  If ever Randy Marsh becomes the next John Landgraff, I'll sell my signed YBMB on fleabay for boatloads of money! (just kidding, Mr. Marsh)
 
YBMB Controls:
The controls of the YBMB are as follows:
Volume - Self explanatory
Gain - Self explanatory, although an interesting tidbit about the gain knob is that it noticeably adds volume in addition to saturation. Another quirky thing about the Gain knob is that at the last 20% of the pot's rotation, it adds even more top-end bite and "zing" to the tone.
Tone 1 & Tone 2 - Tone 1 is the tone knob on the original BluesBreaker schematic. Tone 2 was one of the mods done by RandyMarsh to make the YBMB even more versatile. In essence, Tone 2, in terms of circuit placement, is similar to the circuit placement of the presence trim pot in an MI Audio Crunch Box. My assumption is that Tone 1 is pre-OD circuit and Tone 2 (essentially a presence control) is post-OD, much like how "presence" knobs in most amps work (Mr. Marsh, pls correct me if my assumptions are wrong).
 
Tone 2 seems to have been wired to add more presence counter-clockwise. Interestingly, at both ends of the knob's sweep, the control seems to be at zero point. What I mean by this is, say, at 4:00 the "presence" is at its lowest setting. Sweeping the knob all the way to around 9:30 bring it to the setting that adds the most presence, then at around 8:00 on the knob, it sounds like the setting at 4:00 again (i.e. lowest setting). It's was a bit quirky trying to figure this out at first, but once you get the hang of it it's easy to dial in your sound. Tone 1 and Tone 2 controls are interactive, and thus the YBMB has the ability to specifically tailor the high-end content of the signal. Since Tone 1 is pre-OD, it has an impact on overall gain whereas Tone 2 can be used more for fine tuning of the highs. While the two tone controls are interactive, they do NOT, by any stretch, have the ability to alter the overall voicing of the pedal. They impart incremental changes to the top end content pre- and post-distortion, but the midrange and low frequency content remain virtually untouched, which is something I really liked about this pedal. The YBMB DOES NOT homogenize your tone.
 
"D" switch and "L" switch - To make the pedal more versatile, RandyMarsh added 2 two-way clipping diode switches. The "D" on the "D" switch stands for diode and the "L" stands for LEDs. "D" switch toggles the silicon diodes in and out of the circuit, whereas the "L" switch toggles between LED clipping diodes and no LED clipping diodes. This allows for a total 4 different combinations for clipping diode configuration. To dial in the stock BluesBreaker configuration, toggle the silicon diodes to ON and turn off the LED clipping diodes.
 
*There are other modifications performed by RandyMarsh to make this pedal a "ball breaker" instead of a cloned BluesBreaker, but I'm not allowed to give out the secret sauce (mostly because I also don't know exactly what he did!)  :p
 
 
Performance and Sound Quality:
The YBMB can be classified as a low gain pedal. It has about the same maximum gain as a Barber LTD, although the YBMB with LED clipping engaged can be perceived to have more gain compared to the LTD. It's also a circuit that doesn't have a lot of volume on tap, with unity volume at around 2:00 on the volume and around 1:00 on the gain (at least on my set up).
 
Tonally, the YBMB is an inherently bright pedal. Don't let this scare you though. It's the kind of pedal that is bright but not brittle, i.e. it obviously adds more high end but the highs can still be considered as smooth. The highs can be dialled down via Tone 1 and Tone 2, however, I found that the sweetest tones from this pedal are best enjoyed by not trying to change its signature tone too much. After about an hour of use and experimentation, I settled on this particular setting:
Silicon Diodes - ON
LED - ON
Tone 1 - 10:30
Tone 2 - 2:00
Gain - 3:00
 
At these settings, on the bridge humbucker of my guitar, the YBMB screams classic rock crunch - think Johnny Winter's "Rock & Roll Hoochie Koo". Switching to the neck single coil will bring the gain levels down to "almost squeaky clean" with moderate picking, but one can get a bit of growl and sustain through heavier picking. Basically, at this setting of the YBMB, the guitar's pickup switch BECOMES the OD switch. Even with the guitar's volume at 10, the neck pickup remains pristine for cleaner, arpeggiated guitar passages, whereas switching to the bridge humbucker can bring the rock, without touching anything else or adjusting any other setting.
 
Another plus point of the YBMB is that it does something magical to neck pickups. Because of the enhanced top end of the YBMB, playing on the neck pickup gets extremely enjoyable. There is a certain hi-fi clarity imparted that becomes very obvious when one is using the neck pickup. The wound strings immediately become clearer and distinct and one's playing nuances and string attack are heard better. The YBMB hides NOTHING.
 
With the YBMB, notes on complex chords ring clear even on its highest gain setting. The YBMB's compression is just enough to let passages played on the higher register to sustain properly with natural-sounding note decay, but at the same time still rewards the user with the dynamic response and clarity that encourages better right-hand dynamics and nuanced picking.
 
Stacking with other dirt pedals:
Because of the YBMB's relatively flat response (at least as far as lows and mids are concerned), it performs admirably as a stacker. Out of a few stacking combinations tried, I settled on the YBMB doing the goosing (i.e. going into other drive pedals and not after). The pedals I tried stacking the YBMB into were the Skreddy Screwdriver and the Freakshow Brown Rabbit. I won't talk about stacking into the Skreddy since there are so many variables with the Skreddy that it deserves a thread of its own, but suffice it to say, the YBMB stacked into the Skreddy sounds excellent. What surprised me though was stacking the YBMB onto the Freakshow Brown Rabbit -- it sounded like a raging, hot rodded British amp! The YBMB made the Brown Rabbit clearer, brighter and more forward sounding. It was particularly a blast being able coax feedback on demand from this stacking combo. THIS COMBO ABSOLUTELY SCREAMS!
 
In summary, the YBMB exceeded all of my expectations about the BluesBreaker circuit, and the fact that Mr. RandyMarsh was able to make an already good sounding circuit even better is a testament to his good ears and technical know-how. Muchos gracias again to Mr. RandyMarsh for his excellent work on building the YBMB. The YBMB is certainly a great addition to my rig   :mrgreen:

Indeed it does! And BTW, thanks for taking care of the YBMB while it was in Manila  :-D

I actually wished it was with you for a little while longer so you could have gigged with it.

I really, really hate reading things like that.  I really don't like it because it makes me realize that I still do not have some of the best and the to-trade-my-soul-for devices possible!  haha

The pedal is really a great piece of gear.  I am not even worthy of thanking it's creator, Mr. Marsh, for bringing it into this world and to scuttlebutter for making me experience it.

Kudos too to jdawg for such a wonderful piece of literature and for owning one.  I must also warn jdawg to be extra-careful-- when the opportunity presents itself, I will steal the YBMB from you!  haha

here's a video of the grapadura, taken with a cameraphone...
though it doesn't fully represent what the grapadura can do, it gives you a pretty good tip-of-the-iceberg idea.

here are the settings:

el grapadura:
volume - 9 o'clock
tone - 3 o'clock
drive - 4 o'clock
toggle switches - germanium / ts808 / symmetrical

blues junior:
reverb - 9 o'clock
master - 12 o'clock
midrange - 12 o'clock
bass - 12 o'clock
treble - 12 o'clock
volume - 9 o'clock
fat switch - on

by the way, pasensya na sa mga sabit...   :-)

sir randymarsh i tried your suggestion with the SD9, SUCCESS!!! mids are now much more pronounced! naging versatile na yung pedal lalo! 15k ang nilagay ko sa R12, and as suggested, i changed the value of the tone pot to 10k..

thanks! big help :-D

more power to you sir! :wink:

sometimes, having more info is bad for someone

.....like me  :-(

i want to mod my mt-2 and wah but im afraid to sacrifice something, "impedance"

Boss Engineers designed their pedals to have output impedance that would match the input of another pedal or an amp right.

by changing component values, does this mean that impedance is affected?
we wont have 99.9999% power transfer diba...

we always match the impedance, always

sir randy, matanong lang... yung 2.2uF in replacement sa "sweep cap" ng VOX V847 wah makes it a total volume expression pedal? I've read from wah-wah.co.uk na kailangan daw i-open yung 4.7uF electrolytic cap sa board to make it a vol exp pedal. However, my friend has noticed na pag i-aangat yung rocker same lang din effect once he rock it the other way. Does that have the same issue with your mod? :?
