my amp make this terrible loud humming sound when its on even if nothing is plugged into it. does anyone know whats wrong with it and what i should do about it? its a peavey bandit 112 and has a spring reverb tank if thats relevent at all. also the humming differs in volume whenever i move the power cord around. thanks.
try pluggin it to some other outlet and see if the humming contunues
Sounds like your problem is related to fluorescent lights, or some other appliance in your home. Light dimmers can also cause this problem. Try moving the amp to a different location or plug it into a different socket.
