Hi, just a quick visit from the DB forums, where we have no techies! I'm using a (passive piezo) DB pickup which sounds best through a certain preamp which has a "Phase Reverse" switch. I have a new preamp which I'd like to use with no phase reverse function. Is switching the phase of the signal as simple as swapping the wires on one end of a patch cord, or is it more complicated than that? If it's that easy, all I need to do is alter a cord to use with that pre. If not, what next? Any and all replies appreciated.
