Bought a used peavey bandit 112 Bleu stripe. Volume when turned up even slightly is massively loud, as in shakes the walls of my house. I've cleaned the pots and jacks and after waiting 24 hours for it to dry up, took forever and amp wasn't working, the problem remains but is now present on the post gain volume where it wasn't before. Are the pots bad or is it another circuit that needs to be replaced?
