Continued: Stock 3 point bridge replacement on 2009/12 Epiphone bird, with Babicz aftermarket replacement bridge.
It's a little bit difficult to take a photo of, but down in the bushing hole nearest the volume knobs there is a small hole and there appears to be a little wire poking through there. I assume this is a ground wire for the electronics.
There was talk of putting epoxy or glue on the bushings when they are re inserted to the body. If that happens, I assume there is a chance of putting a barrier between the bushing and the wire that it should be making contact with.
