Upgraded my old RC10 to the RC500 and ended up building new loop board
Main signal splits into 2 channels. Main signal gets split into 2 mono signals to two amps- channel A. Channel B is only drums and loops (or main signal included) and split into stereo into 2 other amps. Both channels are blended via volume pedal. 4 amps and 1 extension cabinet. Sound in my cave is unreal. Been standing here 3 days. Ears are ringing
