Hello! I am trying to run two amps off of a stereo Chorus pedal (Boss CE-2). However, as soon as I connect one of the amps I get a horrible buzz - like bad grounding. I've tried switching cables, amps, running the pedal off battery instead of mains, even changing the pedal for a different one - still the buzz persists. By themselves the amps are quiet. By itself, the pedal is quiet. Together they are buzz city! Any ideas what this could be?
