Wiring up the Jack
This is part 5 of the video series on wiring up guitar electronics.
In this video, I show how to wire up the jack. I’m replacing the original Epiphone jack with a Switchcraft L12A. The L in the part number indicates a longer 3/8” bushing, which is just a bit longer than the Epi jack. I’m hoping this well allow me to fit a lock washer in addition to the regular washer and nut, so the jack will stay tightly in place rather than falling into the body of the guitar so much (as I showed in my Don’t Know Jack video).
I also demonstrate how to use a multi-meter to identify which lug should be ground, and which should be signal. My meter is a Mastech MS8229. If your meter doesn’t have continuity mode (beeps whenever a connection is made), you can just use resistance mode and look for 0 resistance to indicate a connection. Note the L12A has a third, middle shunt lug, which you can just ignore.
