Hi gang! I'm building a P/J bass with two concentric pots, one for each pup. I'm also adding a 3-way (on-on-on) pup selector switch. I've soldered before and I'm good at reading a wiring diagram. I've been to the Fender website and got the wiring diagram for the '62 RI J bass, which has the concentric pots. Unfortunately, there are no diagrams that I found on how to install the 3-way switch. (The Duff McKagan bass has a 3-way switch, but Fender does not supply a diagram for that model.) Anybody know where I can get a wiring diagram? Or does someone already have one they can post or send to me? As always, I appreciate any help I can get.
