Been looking into the Gamechanger with piezo, but I have a question about the dual output jacks. Are they simply for use to send the piezo, if engaged, to a separate amp, or is there more to them? For example, could I send the magnetic signal to two different amps? Even further, could I program it to send, let's say, the middle single coil to one output, and the bridge humbucker to the other for a full range of sound?
