hi anyone have any schematics for a simple guitar mixer to mix two or three bass guitars into one bass amp to save me unpluging during a gig, i have tried an a/b/c switch which does work if you remember to hit the switch when you change guitars but im thinking with a mixer it would be a lot quicker many thanks

hi im looking for a schematic for a carlsbro stingray lead 100 combo i think its one of the later one's ( black ally front panel + parametric + sustain controls ) the amp is dead and has some burnt resisitors on the power board ,any help would be greatful
