[QUOTE="ryan9896, post: 77366, member: 2633"] i have on of these amps, and i do not have this problem....the amp does have ALOT of gain "hiss", but my clean channel is perfectly quiet. there is a "GND-LFT" switch on the back of the amp. if you have a bad ground in your house (or wherever it's plugged in) it will cause constant humming or buzzing. also, i noticed in my bedroom when i plugged it in there was a humming noise, and it only happened when the light was on. certain lights or other EMF sources will interfere with any amp too, so maybe move it into another room and see if it goes away?? also, try switching the GRD-LFT button to see if that helps.
