Solid State Guitar Amp Forum | DIY Guitar Amplifiers

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

This is really easy to do. You need only a follower with three resistors to the input. Each guitar or bass connects to one resistor and that is it. The question is do you really want to. If you do that, each guitar connected will contribute to feedback and noise unless you turn the volume down on each one that is not currently in use. It may be altogether easier to continue with your abc switch. If I can figure out how to post a schematic, and you still want it, I will draw one up and there you go.
