I need help with Stereo P-J wiring!

    I've got an old Fender P that I added a Jazz pickup to in the bridge position. It has the original split coil in the neck position. I've also turned it into a fretless, not that it matters.
    I want to send each pickup to its own volume and tone pot and then to a stereo (TRS) output jack so each pickup can be sent to different effects/amps or inputs for recording separate tracks
    What I'm looking for is a wiring diagram. I've searched the net and I'm not having much luck. Can anyone help?

    Have you considered adapting the Rickenbacker 4003 wiring diagram off their factory web site?

    @mark Holiday ,
    It seems you just described exactly what you need to do. What piece are you missing?

    It's just two bog standard V/T circuits.

    Thanks,
    John

    LOL, sort of, Just which leads go to which of the 3 terminals on the pots, where do the caps go? which lead goes to the tip, the ring, and the sleeve?
     
  7. Use a Pbass diagram separately for each pickup. When you get to the output jack, both grounds to sleeve. One hot to tip, one to ring. I’d probably connect the split P pickup to tip so that, if you use a mono cable you’d still have that sound working.

    250 K pot for P pup and a 500 for the Jazz?
     
  9. If you want. There’s no absolute. 250K ohm tends to cut a bit more treble then 500 K ohm. If you don’t like the tone with 500K ohm volume pots, turn the volume or tone down slightly.

    A couple of things I would consider if it were me doing this job.
    1: I would probably wire the volumes in Jazz bass style, that is to say with the pickup going to the wiper of the volume pot;
    2: I would link the tone controls up to the wiper side of the volume pots;
    3: I would put in a toggle or push-pull on one of the controls to link both outputs back to the tip, in the (likely) event that I wanted to go back to a more traditional setup or get access to the blended tones (hence the Jazz wiring).

  12. I meant to mention that and forgot. Like @SteveCS said, add a toggle or push/pull so both signals can go to tip on the output in case you’re somewhere you don’t have a cable with TRS plugs or don’t want the outputs separate. I guess I did mention the P pickup to tip but I was going to add the switch as another option and forgot. I’ll go be quiet now... :D

    Thanks for all the help. The Bass never leaves my studio, lol, neither do I! I wired it up straight stereo. It works great and does what I want it to. I can now record one track from each pickup.
