Ampeg B2R no volume, low sound that is distorted
 

Saw another post regarding this, but there was no conclusion.

Bought a used B2R Saturday. Worked great in testing, worked great for about 20 minutes once set up at home. Then......

1) Volume is very quiet, and the volume/gain knobs do not affect the volume, it is at the same level always (almost inaudible)
2) Hiss does increase when increasing volume.
2) Limit Light flashes with every touch of the string
3) All sound that does come out of the amp is distorted.

I tested all cables, fuse, new battery in active bass, etc. Pulled the case off the amp to look for obvious solder breaks, or fired components. No issues seen, and no electrical fried smell.

Curious if anyone has had this issue on an amp before and what the resolution was.

Cheers!!!

Wish I could help, but I'd be looking for my money back before getting into fixing it.

Was the fan ever on?

Yes, the fan turns on as soon as the amp is turned on.

I tried a couple other items last night (plugged passive bass in, guitar in, and ran a cable from the loop send and return ((same cable - read about this on another forum)) which made no changes.

The seller has offered to work out a return of $, or to be for the repair depending on the cost. I can find this amp farely cheap used, so I'll have to see what a repair would cost.

Okay...mine had a fan issue and would overheat having the same issues you are having. That was a cheap repair. With all of the new stuff out there, I would return it and put your money towards an Ampeg PF-350 or 500. They sound great.
