My B2 is making an odd buzzing/vibrating sound. It appears to be coming from the Tremolo/Reverb area of the amp. How should I approach this? My B5 seems to be lazy with the reverb, as well...

Could be a poor connection somewhere.. allowing 60 cycle hum to be present.. More or less like an open mike cable w/o mike. Don't know if this describes your problem but hope this give s direction to go to a solution.

More detail please, is this all the time or only when notes are played.
Do any of the controls effect the noise if it happens all the time?

Its buzzing all the time. It's almost like a chirping noise. Similar to Morse Code. Sometimes the volume cuts out in the middle of a song and fiddling with the Bright switch seems to help. The right side channel works fine. Reverb is absolutely off the charts... when the volume doesn't cut out. The effects work fine. It's just this Morse code dit-dit-dat-dat noise that's ever present when the amp is on.

However, I have both B5 and B2 slaved together using the RCA jack. The B5 works fine through the B2 at all times. I plugged in the B5 straight to the cab and the noise is not there. So it's obviously the B2 head. I'm guessing it's coming through that left channel...

Try unpluging both of the cords from the reverb pan where they plug into the circuit board, and be sure to note which cord goes to which jack before you unplug them, and see if that effects the noise.

Okay, I'll give that a shot. Would it still do it with the reverb off?
