I've been using my GK 700RB and Avatar CB112 with my BugBass with great success in the 4 piece jump blues band. However, at the last gig, I needed more volume than usual in a room filled with hard surfaces...turned up the input gain and boost a bit, along with a bit of hi-mid. All three gain stages were about straight up. It sounded a bit too nasty that way and the guitar player thought I might have been clipping the amp. My guess instead is that I'd accidentally set up my sound for the famous GK growl, which may not be the best tone for a EUB. I backed off the hi-mid, added a touch of contour, backed off the boost a bit and pushed the master...produced a much warmer sound with the same volume. Anybody else run into this with EUB or URB?
