Both tone controls are permanently wired in parallel. As a result, one is redundant.
Is that what you wanted?

That will be difficult. It's easy to wire a tone control directly across a single pickup, but to place one across two infers that both are always on together or that you need a special wiring design. What switches are you using? You could use two SPST switches for each J pickup and a DPDT Center-ON (DPDT ON-ON-ON or SP3T) toggle switch to select [J pickup(s)] or [J parallel P pickups] or . This method can have a tone control for the J pickups and one for the P pickup. Both tone controls will be active in the [J parallel P pickups] mode.
You could as well use a DPDT Center-ON (DPDT ON-ON-ON or SP3T) toggle switch to select [one J pickup] or [both] or [the other J pickup]]
AND
another DPDT Center-ON (DPDT ON-ON-ON or SP3T) toggle switch to select [J pickup(s)] or [J parallel P pickups] or .
This is similar to the wiring in my Fender Stu Hamm bass, except it uses a blend pot for the J pickups. www.fender.com/support/diagrams/pdf_temp1/basses/0191500A/SD0191500APg4.pdf

Are they 1/4" threaded bushing switches on a pickguard or something else?

^ Chris, If he's otherwise satisfied with his design, why not just change to DPST (or DPDT) switches for the Jazz pickups? the second pole "or"s the two pickups to the Jazz tone pot.

unk, Kinda my thoughts too, but your scenario sounds to me like it would leave the P tone control active at all times. I'd use a DPST switch for each of the three pups, and let the second pole turn on/off the appropriate tone control. There's no getting around the duplication when both the P and at least one of the J pups are selected, but that's nothing new, eh? Hey Tyler, you back for better or worse, or are you just passing through? sumgai

Yeah, this is another (and simpler) way to go. I was biased by how my Stu Hamm works since I like it, and thought that I'd leave that extra hole for a series mode if desired (resonance from another thread). (And I have many of the three-way toggles - if'n I'm gonna drill a hole, I'm gonna get as many throws as possible out of it.)
If a DPDT is used for each pickup, there are enough poles to mitigate the tone control path. It is possible to have each tone control apply to its respective pickup (group), as well as to select which single one (if desired) is active in the P and J(s) on modes.
For instance, if the P tone control is to be the master when the P pickup and at least one J pickup is on, the P tone control can be wired directly across the P pickup and the other pole on the P DPDT can be used to switch the J tone control out in the P on position. Or the other pole can select between the J and P tone controls as it selects the P pickup to be in circuit.
Conversely, if the J tone control is to be the master when the P pickup and at least one J pickup is on, the P tone control can be wired in series thru the other poles on the J DPDT switches and only be in circuit when both J pickups are off.
We actually don't need to switch the tone pots if we are using/sharing the same capacitor. Only the capacitor from ground needs to be switched/directed to the proper pot.
If you need any further help with this as a diagram, let me know.

hey there, I wanted to let everyone know that thanks to ChrisK my fretless bass project if finally done. Chris was very generous and fixed my errors in my diagram. here is his version of it I finished it Tuesday, then picked up strings yesterday. my plan was to put the strings on today and have a glorious time playing my new child. Then I got into my truck this morning, started it as usual. then thought to myself, why does it feel like im sitting on glass? then i look down and noticed that i was indeed sitting on glass. to my horror my car window was smashed and my new child was gone. along w/ my backpack which had my soldering iron, stand, wire cutters strippers ect. and my tackle box full of components. again, i would like to say thanks to Chris and anyone else who helped me with this project. it was much appreciated. Tyler (edited to display the larger drawing, link no longer needed)
