Very odd P-Bass mod request.

    I have someone that wants his P-Bass wired so that the pickup (that is 2 coils in series to make one pup) he wants the coils separate and wants to have the "tone" control only active on the bottom (D&G strings) coil. Any ideas, I'm totally out of ideas. No matter what combination, dual gang pot, push/pull...the tone will always control both coils due to the output summing at the mono output jack.
  2. Yes it will. I believe the old stack knob Jazz basses with concentric knobs had resistors to provide some separation of the controls at the expense of a somewhat lower output. The only other thing I can think of would be an active buffer / blend type control for each pickup half but that’s getting pretty complicated for what I’m guessing the customer wants.

    I'm highly opinionated and extremely self-assured
    Weird. Someone else had the exact same question a few weeks ago.

    My reply was Bill’s P-J Wiring Diagram. Omit his master tone control. His “blend” pot is really a tone pot for his J pickup. So substitute your D/G coil for his J pickup, and your E/A coil for his P pickup.

    Report back if you decide to try this!
  4. If the P is wired as standard (in series), it is possible to have a tone pot only work on one coil. Solder a wire to either end of the short wire that joins the two coils. Then reinstall the pickup so the earth wire comes from the DG coil and the hot wire from the EA. Then run the tone control from that extra wire.

    Another solution is to wire each segment as a separate pickup with its own volume and tone, according to Rickenbacker 4003 wiring with the "Ric-O-Sound" jack, and send the output of each pickup to a different amplifier.
