Re: Got a FISHMAN AST Powerbridge - what type of amplification?
Check out Lehle. They make a Little Dual, that has two inputs, one for mono and one for stereo. Then it's just a simple A/B Box. On the stereo input, input A runs to output A and B runs to B, so depending on how you wire, you would set up your A for either the acoustic or the electric and then B for the other.
