Double Jazz Bass P'ups?

[StarbardGuitar]

Hey, I was looking at the "Tractor" bass and it inspired me to do that for both pickups on a jazz bass. But I'm not sure if it's even possible, or how I'd go about doing it?

(This is what I'm talking about btw, the bridge pickup seems to be two jazz bass pickups wired together)


Ideally, if I were to do this, I would like to have the option of normal Jazz Bass tones (by turning off the extra p'ups) and series/parallel switching. I was wondering, would each pickup set have to be RWRP? How would it sound with all the pickups on also? How would I go about wiring this? I was thinking that you could do 4 volumes, and some sort of switching for the pickups to be in series/parallel, or something similar. Is this even possible? I'm not sure how you would do this because I know to do a series/parallel mod you need a 4-conductor humbucker, so how would the two jazz bass pickups work? They have only a ground and a lead wire. Any thoughts or advice would be greatly appreciated!

He took the neck pickup, since he put the Bi-Sonic there, and installed it by the bridge. So it's already RWRP. The only thing is it's narrower than the bridge pickup.

You can turn off the extra pickup, and get just the one of them.

If you can get a RWRP bridge sized pickup, that would be idea.

Or you can do something like this. This has two Jazz bridge pickups, but RWRP. When used in series they have a big fat tone that matches the output of the P.
