Understanding Guitar Wiring

Output Jacks


The output jack is where it all comes together. The various pickups, pots, switches, and caps eventually direct the signal generated by the pickups to the output jack. Diagram #13 shows a typical mono jack and how it should be connected. Diagram #14 shows how to wire a stereo output jack to turn on an onboard power source (battery) when a 1/4" mono plug is inserted. This works by using the "ring" connector of the stereo jack to complete the ground side of the active onboard circuit when the plug is inserted.
