I recntly purchased a moog sub phatty with the intent of playing bass guitar and synth in the same show. The main problem I'm running into is the drastic difference in gain levels. I'm able to set volumes for different patches on the moog, but I'm putting the volume at 1 and a half or so, so even a tiny knob turn might blast away the audience. I'm wondering if anyone has some direct experience and can recommend an AB or ABY switcj for this purpose. It would need two different volume levels, and possibly an eq, although that could also be seperate.
