I have a Guitar Research wah-wah pedal, but whenever i try to use it it crackles as i move my foot back and forth. I've had it for a few years now, but i havent really used it that much, also the connections to the9-Vsocket thing broke off a year or two ago, but i got it repaired and it was fine afterwards. I'm not sure if it's the connections or something else. Any ideas?
Bad pot, buy a new one. www.smallbearelec.com
the pot may be dirty
^Doubt it, most wah pots are sealed.
it definately sounds like the pot is dirty or broken, smallbearelec.com sells them pretty cheep
I'm so-so with electronics, is it easy to replace or should i ask for assistance or give it to a shop?
Very easy, you just have to unsolder 3 wires, and then solder the 3 wires onto the new pot
