I just got a fender fm 212 dsp from a pawn shop today. Tried it out in the shop and it worked fine. Got it home and it worked fine for a while then it started acting weird. At first it would only play clean and play very loud. Turning the volume control did nothing it just stayed loud then it wouldnt produce any sound. When you turn it on both channel lights are on even if you hit the channel toggle. When you plug in a cable you can hear a buzz but when you plug it into a guitar you get nothin. Any advice would be awesome because I am at a loss

Hi tmac777,

The first things that I would check are the solder joints and circuit traces, possibly a problem in the area of the +/- 16 volt supplies around the big rectangular 5 watt resistors, maybe also the input jack joints, but a thorough check of all joints would be a good start. Re-flow any joints that are cracked or dull, and bridge any broken traces. :idea:
