Abstract: A switching device receives an output cable from a guitar. The output cable has a plurality of conductors corresponding to each of the pickups on the guitar, typically 2 or 3. A passthrough signal based on manually switched pickup selection corresponds to a main guitar output. A pickup buffer circuit on the guitar isolates the signal conductors from the selected passthrough signal, and also switches the pickup buffer circuit on and off to allow for backwards compatibility. A multi-conductor cable and jack simultaneously transmits the plurality of signals to the switching device. The switching device receives the multi-conductor cable. A combination circuit in the switching device combines the signals from the pickups and also delivers the individual pickup signals to a respective output jack. Each output jack simultaneously delivers the respective pickup or combined signal to a mixer, amplifier or other signal processing device for recording and/or further processing.
