What do you guys use if you have , say, your one electric guitar and you have multiple amps and preamps and would like to be able to plug into a single point and switch between them all without having to re-patch everthing?...Sort of a mixer in reverse...instead of multiple inputs and a pair of outputs, I need 1 input (for the guitar) and about 5-10 outputs to switch between , depending on what amp/preamp sound I want.....I've seen 3 way footswitch selectors, but it doesn't necessarily have to be a footswitch.....a rackable box/switch would be ideal...
