....okay, this is in referance to schematics for guitar wiring. Pardon my ignorance, but in every schematic I see shows 3 connections on the switch. At the base of the switch you have a lead in for the bridge pickup, a lead in for the neck pickup and the hot signal out. But what about the other leads that are near the top end of the switch? Is that for a wire to be taken to ground? Not seeing this in diagrams confuses me and I'd just like to be sure of what I'm doing. Thanks.
