We use CTS pots, fiber covered wire, and Mojo Dijon capacitors. We also use a 3/8" long bushing output jack to accommodate right-angle guitar plugs. (ya gotta love that).
A 3-way pickup selector switch with our own, hand shaped, switch-tip.
We use a push-pull switch on the tone knob that will split the humbucker coils. When pulled up, all humbuckers on the guitar go into single-coil mode.
Different wiring configurations are available on request.
