My son's older Peavey bass amp is older (15yrs), and most of the pots have some scratch in them. The local music store sold me some contact cleaner, but I don't know how to use it? The salesman made it sound like you just remove the knobs & spray it on the outside? Does that make sense?
Anything else I can do for a quick fix? I'm not going to replace anything. Just looking to make it a little quieter.
Thanks,
