Output Jacks


I-4000_8

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.
