I bet a lot of you have seen that nifty little device that ampeg dealers have in their stores that switches between 8 amps and 8 speakers. It has the ampeg name on it. Essentially you move one knob to select the amp you want to recieve the speaker level output from and the other knob selects what speaker you want that speaker level output to drive. My guitar player wants to bring 2 or 3 different heads but use the same cabinet. Do any of you know if there is a company that makes a good/transparent amp switcher that is designed for speaker level signals besides the one for ampeg dealers?
