Title: How do you deal with noise?
Post by: ubersam on May 31, 2007, 08:27:08 AM
In my time with guitar/gear related forums, I have come across plenty of discussions about noise gates, noise reduction devices, etc. More often than not, only the devices are discussed and there are no discussions about the source of the noise or how to address it. Noise reduction/gating/filtering devices are not the be-all/end-all solutions to noise problems. Noise can be from a number of sources, anywhere from nearby electrical/RF/magnetic activity, insufficient shielding, improper or inadequate grounding, to just plain noisy devices. The noise should be addressed at the source. It can be a lengthy trial-an-error process but any noise reduction/gating/filtering devices should be the last thing you would implement, and only to address either any residual noise that the other solutions did not clean up, or in some cases, if everything else fails.
Examples causes and possible solutions:
Noise due to an improperly grounded amp: Ground the amp properly.
Noise due to dying or microphonic tubes: Get new tubes
Noise due to transformer (as in an adapter) with a big EMF in the vicinity of a sensitive device: 1. Move sensitive device away from the transformer; 2. use mu-metal to shield the transformer or the sensitive device; 3. get a transformer with a smaller EMF, like a toroidal transformer.
Noise due to ground-loop: break the ground-loop (here is some info on ground-loops and how to address them: http://www.rane.com/note110.html (http://www.rane.com/note110.html))
Noise due to a noisy guitar: 1. Shield the guitar; 2. Check the guitar's wiring, a star-grounding scheme might be in order (check here for more info on shielding and star-grounding: http://www.guitarnuts.com/wiring/index.php (http://www.guitarnuts.com/wiring/index.php))
Noise due to a dirty/unfiltered power supply: 1. Get a better power supply; 2. Filter the power supply (this applies to AC power as well as DC).
Noise due to a microphonic p-up: 1. Re-pot the p-up; 2. Get new p-ups
Noise due to noisy effects circuit: 1. Have the effect modded to minimize, if not remove, the noise; 2. Get a better effects pedal
Noise due to excessive high-end content (hiss): 1. Bring down the treble/prescense, i.e. adjust the tone control settings; 2. Could be high-gain hiss: either turn down the gain or try cleaner sounding preamp tubes.
These are just a few examples off the top of my head. There are other causes/sources of noise and specific solutions to correct them. For instance, midi signal ground is isolated from the device's chassis ground. In my midi-controlled rig, one of the midi-plugs developed a short between the ground pin and the shell, causing a ground-loop. I had a tough time tracing this noise source. I ended up removing devices one at a time and checking all the plugs before I found the culprit.
There are also some situations where a noise gate of some sort seems to be the only choice. For example: I have a Mesa Boogie Triaxis preamp. I absolutely love the tones from this unit. However, some noise can be observed when in the high-gain presets. The guitars I use are already shielded and star-grounded, so that takes care of that possible noise source. Then there is the lone wah pedal that I run through, which is in a midi controlled signal switcher (looper). Whether or not the wah is in the chain, the noise is still there, so it is not the wah. If I plugged the guitar straight into the preamp and there is still noise. After the trial and error approach, I came to the conclusion that the noise coming into the preamp is exaggerated by the nature of the high-gain circuitry, nature of the beast so to speak. Could have been the p-ups being noisy but I like the p-ups and did not want to change them. I even tried using lower gain preamp tubes and/or cleaner sounding tubes. The results were either the noise was still present, or I did not like the tone. So in this situation, it seemed like the only logical solution was to use a noise gate.
The only question then was, where to place it in the chain. Before the wah? After the wah, before the preamp? After the preamp, before the power amp? There really is no one-and-only correct answer. It is up to you (or me in my case), where the gate will go, where it will give the best acceptable* result. Trying it before or after the wah seemed to have the same result, which was better than having it after the preamp. Having the gate after the preamp did not sound and feel natural to me. So, I just decided to have it as the first device after guitar and placed the gate before the wah. This give the preamp a cleaner signal to work with, there is a smaller noise level that the high-gain circuit can exaggerate. This was also gave me the most natural sound and feel (response). I also ran into this question when I was playing around with a pre-mod SD-1, and came to the same conlusion: place the gate before the noise generating device. After the mod, there was very little need for the gate.
*Acceptable results: Many times, a player gets too focused on getting a pristine, clinically clean sound. It might not always be attainable, in some cases you might have to sacrifice something to attain it. A player needs to determine what amount of noise is acceptable to him, and at what cost. Will the audience notice, or even care, if there is a minute amount of noise? Will the amount of noise be noticeable once the whole band is playing? Is the player willing to sacrifice the feel or vibe of his rig just to attain hospital-white cleanliness?
Anyway... Just some random, unsolicited thoughts about noise and noise reduction/gating/filtering solutions.

Siguro po sir I'll just add good shielded cables, good connectors and clean contact points. Minsan din po kasi pag madumi yung contact points nagkaka noise.

Minsan din po kasi pag madumi yung contact points nagkaka noise.
yung gitara ko dati nag kakaron ng buzz sounds e, tas ayun pag silip ko sa jack may mga amag amag na ewan na kulay green. haha. .....madali lang yung solusyon, nag bilog lang ako ng sandpaper tas inin out in out (sorry la ko maisip n term hehe) ko dun sa jack, ayun wala n yung mga dirt na nag caucause ng buzz. ......nag caucause sila ng buzz kasi di na maganda yung pag contact ng cable dun sa jack.
tas eto natutunan ko dun, .....tuwing mag sasaksak sa jack, punasan muna yung cable ^_^ ......sana nakatulong hehe

How do I deal with noise? I call the barangay. :-D
Sorry korni. :(
Seriously, I dealt with this problem through trial and error-- very expensive error. I bought a noise gate thinking this would cure the problem but no! I soon found out, that the noise generated by the guitar actually came from cheap patch cables. I solved the problem by making my own patch cables, which i learned through trial and error too. Then I sold the noise gate. It still has that hum which BAMF told me might be coming from computer monitors. He was right. :-)
There's this one time when I brought my Fender Ri project to Jon (elegee) for him to put together. He asked me if I want to paint the cavities with "anti-static paint." I asked him what it was but his answers just flew over my head. What I pictured in my mind though was a scene in Spinal Tap when the band's playing in an air-force base and the sound of the radio is heard through Nigel Tufnel's gear. :-D Aahhh. So that's what it's for.
I learn from masters here at Philmu so thank you, Sir Ubersam, I learned new things today. Always a great feeling.

sorry po kung me napadpad na [grape] dito di ko lang po maintindihan tong mga terminology nato:
Noise due to an improperly grounded amp: Ground the amp properly. (anu po ung ground?)
2. use mu-metal to shield the transformer or the sensitive device; 3. get a transformer with a smaller EMF, like a toroidal transformer. (anu po ung mu-metal? tsaka pnung smaller EMF?)
Noise due to ground-loop: (nkita ko po yung link, anu po un kelangan ko pang kalasin mga cable ko?)
at anu po ung pinag kaiba ng regulated sa unregulated? nakasulat ba to sa mga power supply pag binili mo? at anu advantage and disadvantage nila?
at ung anti static paint, or anti ekek merun kasi ganito dad ko san po kaya pwdeng ilagay to?
Tip: Always keep the signal wires as short as possible at ilayo sa supply wires. (anu po tong mga to? at anu pinag kaiba nila sa isat isa?)
and how do i know if the cable is shielded?
sorry po madaming tanung, di ko po alam, pero binabasa ko na po sila, kaso mas madaming nabulagang terminologies sakin e, sana po me me mag elaborate salamat po

let me add that it also helps pag maganda yung cables nyo.
better cables let more of your signal through. they also have lower capacitance, which allow more high frequencies to pass through. as a consequence, your guitar sounds louder and brighter in most cases, forcing you to turn down the treble in your setup. this will reduce hiss and noise.
YMMV. btw hindi mo naman kelangan ng super mahal na cables like vovox, two-rock or van den hul to actually hear a difference. sometimes an upgrade to planet waves or dimarzio from your generic JB or RJ cables is enough. pag kulang ang funds, start with the cable between your guitar and your first pedal. :wink:

hi guys,
need a little help here:
MXR distortion plus clone:
I am posting this to ask for advice from DIY stompbox builders on how to remove that humming/noise. I have used the project file from general guitar gadgets and basically bought the components from our local electronics stores here in manila and built everything myself. i even used shielded wires and grounded the shielding.
it's all running now except that noise. ive benchmarked the amp settings using my behringer UM300 so i know its not the amp settings.
hope you can send in advice soon so i can finalize the assembly on the casing. below is the link to my project build. thanks.

Yung signal cable mo nakapatong sa PCB. Try mo ilayo. Kung hindi pa rin nawala, hanggan dun na lang talaga yan yung design ng circuit. Besides, distortion yan dahil ang mga distortion ay high gain, pati noise na amplify. Ang target natin ay maminimize yung noise na napipick-up.

sorry po kung me napadpad na [grape] dito di ko lang po maintindihan tong mga terminology nato:
Noise due to an improperly grounded amp: Ground the amp properly. (anu po ung ground?)
2. use mu-metal to shield the transformer or the sensitive device; 3. get a transformer with a smaller EMF, like a toroidal transformer. (anu po ung mu-metal? tsaka pnung smaller EMF?)
Noise due to ground-loop: (nkita ko po yung link, anu po un kelangan ko pang kalasin mga cable ko?)
at anu po ung pinag kaiba ng regulated sa unregulated? nakasulat ba to sa mga power supply pag binili mo? at anu advantage and disadvantage nila?
at ung anti static paint, or anti ekek merun kasi ganito dad ko san po kaya pwdeng ilagay to?
Tip: Always keep the signal wires as short as possible at ilayo sa supply wires. (anu po tong mga to? at anu pinag kaiba nila sa isat isa?)
and how do i know if the cable is shielded?

sirs, how will i know the cause of noise... for example in my case, I can't figure out what's the cause of noise in cheap gears.. I'm using grg121 (all stock,4 mos old) direct to my practice amp (Laney LX12, 3 mos old) using the cable that comes with the guitar.. I recently having problem with the noise cam out of it, and I don't know the cause.. I wish it's just the cable.. :x

Sir, how do you "properly ground" the amplifier, or the is it the guitar?
thanks.

thanks.
if you have the luxury of opening up a guitar amp, all the grounds must be connected. grounds connecting to only one point is not really that necessary, but you must ground all points that need grounding. avoid ground loops.
kung hindi mo naman binuksan, check mo yung plugs. dapat yung isang pin ng plug e nakasuksok sa 0volts ng outlet. i read sometime that this is because supply electricity to our homes has a phase.
kung ayaw pa din, sometimes tying a wire around the jacks (that plug into the amp) and connecting it to ground/Earth (lupa, semento, etc.) helps a lot. yung ibang maarte ayaw nito (papangit daw itsura), pero if this serves the purpose well, why not?

and one more thing: go easy with the Dist/Drive/Fuzz/Dirt knob on your pedals. the result is attenuated noise and clarity of course. pero shempre hindi ito ang pinakasagot sa lahat ng prob sa noise.
