I get a terrible scratch sort of noise when I turn the volume know on my Jackson. I'm not sure what's causing it.

I'm not too familiar with the electronics within a guitar, but random browsing has lead me to believe that it could just be a dirty pot possibly, or bad wiring.

My pickups are Ibanez V1 and V2's, and I sometimes get it when I turn the volume know, and it usually only happens on my bridge pickup, which I play most. Would a dirty pot be a good place to start? What could I use to clean it with?

I've read about Deoxit before, but I can't find a place to get it in Canada. Could someone recommend me a way to clean the pots without Deoxit/What other cleaner I could use?

Just spray some electronics cleaner (contact cleaner, Deoxit, whatever they call it, just make sure it says electronics on it) into the pot and turn it back and forth a bunch of times. That should fix it but if not you can just replace the pot... Not too expensive or difficult to do.

"No rub," eh? And that's why that contact cleaner will not work. Eyes are different from pots.

The guitar is fairly old, so I assumed it was the pots. I'll find some contact cleaner today and try it out.

Also is has a switch for coil splitting, I'm not sure how it's wired but I really have no use for it. If I were to remove it could I put it in at a later date if I wanted to?

Of course you can, you can rewire your guitar at any time to whatever configuration you feel like. Here's a tip - photograph everything before you change it. Digital cameras are a tech's best friend.

Cleaning a pot is a stop gap measure at best. Just replace it.

I'm not familiar with electronics in guitars.

I notice that the pots are cheap, but what difference do they make. If I took a 250k and replaced it with a 500k, or vice-versa, what difference would it make?

A 500K pot will result in more top end.

Dave Grohl is the best

I don't mean to thread jack, but I have a quick question that is on-topic:

Is it normal that when I'm getting a lot of noise in my rig that it increases towards the middle of the taper of my volume pot? As in, if I set the volume to "5", it's more noisey than when it's at either 10 or 0

Is that normal?

Also, I've been thinking about replacing my pots. What's a good brand to go with? The only one I'm even aware of it CTS.

CTS aren't what they used to be. Go for a Bourne.

That is just showing you that the guitar is noisy. You're increasing the signal strength and part of that signal is noise. So the noise is emanating from before the volume knob (or the volume knob itself but that is unlikely in your case). So pickups, grounding, sheilding.

It's prominent in the middle of the pot's "sweep", though. Like when it's on 5 it's obnoxious, on 0 it's nonexistent, and on 10 it's not very noticable.

That's because the wah is a bandpass filter. It's noisiest when it's dialed into the same frequency as your noise.

That could be a dodgey pot then. Don't **** around, just swap it out. A pot will cost you about $5 and it's something that you should know how to do yourself.
I particularly like ALPS pots but they are pretty big and you really need to have little PCB mounted on the back (I bought a heap of them off ebay for peanuts) and they are quite expensive. Try to find a Bourne and failing that a CTS. Make sure that you get a log/audio pot for the volume.

Just find one the same value. Some people like log/audio in there and some like linear. If you hardly ever move the tone control far from full, use linear. If you tend to use the entire range a lot and spend a lot of time with it turned way down go log.

You may want to consider replacing the tone cap at the same time, depending on what's in it. If it's a el cheapo greencap, replace it with something decent. I use Russian Military stuff but an Orange Drop would be good enough.

Nah bro, it's cool. I'm actually learning things from your conversation..

So I took the control plate off my rhoads and the wiring is an utter mess and dirty as can be. So I'll clean it with contact cleaner for now, but I might take it to the local tech to give it a look afterwards. The wiring actually looks, for lack of a better phrase, dangerous.


Also, if I want better pots, what ones should I look at, brand and Ohm wise?
