Hey guys,

Just recently my peavey 5150 started making a popping noise while im playing and it even does it when i am not playing. also the volume will suddenly drop to a lower level and then go back up later. ive tried defferent cabs and guitars and it still does it. i just added a korg tuner, bbe sonic maximizer, and a boss noise suppressor pedal and im not sure if that has anything to do with it either.

can anyone help?
well try going without the pedals....

if it still does it, check the tubes/fuses
