so ive been looking at building a P-Bass, buying a body, neck, pickups, pickguard etc. and putting it all together

however, ideally i would like to have the ability to have the tones of a passive p bass and an active p-bass in one bass. Is there some sort of tone circuit that i could put in to make this possible, the ability to switch one pickup between passive and active? Or would it be a feasible option to put a jazz pickup in the bridge, and have that be active while the p was passive?

EDIT: I've decided that what I definetly want to do is put the passive P pickup in the neck, and an active J in the bridge. Can anyone find me a schematic for it? Seymour Duncan doesn't have any like it. If possible, i'd like to somehow make the jazz in the neck able to work as a passive and active, but its fine if this isn't accomplished

Tenative Specs:

Body: Alder
Body Shape: P Bass(would consider a Jazz as well, will have to sketch it all out)
Neck: hopefully looking for all maple, probably a traditional P headstock
Neck pickup: Seymour Duncan quarter pound P Bass
Controls: Probably just one volume, one tone, and some way to switch between the neck and bridge pups
Bridge: probably a Badass II
Finish: Light Blue/Light Teal
Pickguard:
Arbor A410 Bass
Dinosaur 20 Watt Bass Amp
Line 6 Spider III 75 Watt
Squier Bullet

Excuse me sir, have you been thinking tonight?

as far as i know, there's not a way to make a pickup active or passive, you could use an active preamp, but i'm not exactly positive about a/p switching.

sorry... but i'd like ot see your paint options! :d:

that is a good idea... maybe ill consider using an active preamp

but as for paint..... im doing a very light teal or light blue body(think a mix of daphne blue and surf green), with a checkerboard pickguard that i found online

with some active preamps like bartolini they give you a oush pull pot that means you can switch from active passive

but do you want active pickups or what because it doesnt give you a great amount if variety in the tone

so far as i know you cant make a passive pickup active or vice averse. Check out the fender website for schematic's
or

and i think that if you run the whit wire on the p pup and the white wire on the J pup througha 3 way on\on\on switch in a different orde you can switch form neck to bridge to both.
im not sure on any of this

Nice pickguard... but that's not a bass pickguard. It's for a stratocastre, which is a guitar.

ummm, thats a strat pickgaurd and youd have to run two circuts, then join them near the output and also conect all controls. i can make a schematic but its confusing and not worth it, the sound you get you could just get with a good amp

Carvin makes preamps with active/passive switching as well. The thing is that the switching is for the whole preamp, not individual pickups (and I don't know if that's possible). And as for the pickguard, you probably just want a standard P bass pickguard--on most basses the pickguard doesn't extend all the way to the bridge pickup (see just about any Fender bass).

Sounds like a nice build overall, and the P and J combo sounds nice.
