P - J Bass Blend pot problem.

[RGZ184]

I'm wondering if I got a bad pot on this. I wired up my P-J bass with a Master Volume, Blend Pot, and a Master Tone, on 1 end of the blend pot I have the precision pickup on full, but when I turn all the other way to the jazz pickup, it fades out. In the middle you still get the blend of the 2 pickups. Should I consider getting another blend pot if that's the cause? Any tips are great.

Hmm, if you can post some pics of your wiring, we might be able to figure out what is going on. I wouldn't rule out a bad pot, though.

Sounds like the blend pot is wired up wrong.

Certain blend pots are not reversible. Especially the M/N taper pots like a Bournes.

Also keep in mind the P will always overpower the J. So the center position won’t be a 50/50 blend.

This has always been an issue. Also, the J will hum, and the P will be quiet. This is why many people search for a more powereful, hum-cancelling J pickup in P-J basses.

Back in the late 70s I had a ‘76 P bass with two P pickups.

That works great and to me sounds much better.

Same idea here.

BC Rich was doing 2 P-Bass pickups in the 70s, too.

To me, the P-J thing only kinda works. It isn't 'the best of both worlds', and doesn't make a P sound like a J. I think the idea is nice, but I've never heard it executed perfectly.
