What I meant was I bypassed the GT10's preamp, and used it as a stompbox set in front of my amp. Sweet bro! The only problem is that my amp has no FX loop, so I was not able to use 4CM. Everything was in front of my amp. Before this, I've always used the GT10's preamp and plugged either directly into PA or into the power amp in/FX loop.
IMHO, it's best to bypass/turn off the GT10's preamp if you like how your amp's preamp sound. Just use it in stompbox mode.
We (Markd) have the same honest experience and opinion....Sana nga nag labas ang Boss ng two Flagship version ng GT10
one is our current GT10 version w/COSM preamp models
the other is GT10 version without COSM preamp model para cheaper
Guitar amp has two major circuit stage just to illustrate.
INPUT (preamp stage) and OUTPUT (amplifier stage)
then out to cab/speaker. Some has effect loop in between SEND out galing sa preamp stage and back to RETURN amplifier stage. It can be parallel or series or both. Some has their own Mojo on each stage din.
back again to our manual page 25. Set
output select to JC120 or Small Amp( if small wattages amp/speaker is/was available that time) or Combo or Stack
Boss meant when using FRONT INPUT co'z they gave user other options for RETURN
JC-120
Use this setting when connecting to Roland’s JC-120 guitar amp.
SMALL AMP
Use this setting when connecting to small guitar amp.
COMBO AMP
Use this setting when connecting to the guitar input of a combo amp other than the JC-120
guitar amp (where the amp and speaker or speakers are combined in a single unit).
* Depending on your guitar amp, you may be able to obtain good results with the “JC-120” setting.
STACK AMP
Use this setting when connecting to the guitar input of a stack-type guitar amp (where the amp and speaker or speakers are separated).
Set those Guitar amp INPUT channel 1 clean (or eq/tone into clean and flat) plus better if you have channel 2 dirt (for your OD/DS) then have ready with your amp footswitch beside GT then use the GT in MANUAL mode like a analog pedals
for example lang.
P1 Comp
P2 OD/DS (Just use Fx1 or Fx2 if you love your amp channel DIRT)
P3 Chorus
P4 Delay
B1 patch up
B2 patch down
Ctl1 switch between PATCH mode and MANUAL mode
Ctl2 FX1 or FX2 (whatever you like other than FX1/2 or as TUNER)
Exp pedal to switch ON/OFF wah OR Volumn controlling and for solo boost
This is good to many
1. You can use your own clean and dirt guitar channel preamp
2. can use various OD/DS on P2 with B1 patch up/ B2 patch down
3. If you don't have a RETURN loop on your guitar amp
4. You can easily change into PATCH mode with Ctl1 whenever you wish to exit to MANUAL mode
5. If you really don't use GT preamp so not to double stack in series a sim preamp with your guitar preamp. Result it would sound compress(thin/harsh) like chaining both distortion box or one od and one dist BOTH switch ON even od is set to clean. Now to compensate that thin sounding we opt to push the volume more on either stomp which again would resulted to FEEDBACKing still would also compressed the signal and its not wide open just unlike ONE STOMP od or ds. Better use an OD or DS stomp series with clean BOOSTER stomp di ba Sir. Clean and transparent ang overdrive or distortion with the booster stomp. Maganda sir yon Mosfet booster ng AMZ sa akin pag analog pedals and set up ko. Maraming iba pa.
Caveat, when you make or build and save a patch aimed to a specific AMP your patch may not sound the same with another AMP and this is true in my experience. One solution is Boss gave us the Global Eq Function see our manual page 62
So you won't reset every patch and leave it untouched BUT this is not guarranty 100 percent. Even some multiFx has this global function.
Also when you built your patch in low volume at home it may also not the same when you use it LOUD live with your band so better tweak the basic level at home then re tweak that high with some eq needed to compensate the Fletcher Munson effect then save write/save it LIVE Hotel California just an example or make some code like L/Hotel hindi Motel ha
To give some idea on FM
here
http://en.wikipedia.org/wiki/Fletcher%E2%80%93Munson_curves Again there is no RULE lagi ko nalng inuulit ito. Kasi anyone everybody has their own various type of guiatr/gear/rig/tone/experience/mojo etc....
If it is sound good to you then its great. I or we can't say pangit yan mas maganda akin or mas maganda yon. Hype or Facts
THERE IS NO RULE OF THE THUMB
BTW, this is the very reason why also I started the DEC or HARMONIC CONVERGER (HC) thread for that topic not to discuss it here, kasi di ba many are enjoying their multiFx even GT10 as stand alone mga comrade. And we would like to discuss tip/trick/sharing with GT10 here co'z we don't want to offend those user specially GT10 owner here then later demoralized sell their unit then frequent flyering here pangit GT10, hindi talagang pangit GT10 (of course they are entitle to their own right opinion) mawawalan na naman tayong kasama. If someone, someone only asked some issues here or maybe solution related to the best you know DEC or HC could help just point that thread and may say "last option sir subukan mo na lang muna DEC or HC baka makatulong sa problema mo kung hindi pa sell it"
Here's mine only analogy
Pineapple is not for everyone, I don't like Pineapple no joke that is true! kasi nanganga sim ako kahit matamis sikmura ko after I ate and I don't know why? siguro nag yo yosi kasi ako BUT i know its full of vitamins not just C and good for the health. So I sort to Apple or ponkan Orange na lang kasi mura na.
Hope I did help and explain it well from my POV.
