Jaguar pickups - problem.

Hello!

Today I got 2 fender jaguar 62 AVRI reissue for my MIJ jaguar.
I wired them "by the book", black wires to ground and yellow wires to the switches.
Sound great when I play on bridge pickup OR the neck pickup and I can really hear difference between the AVRI to the MIJ pickups.
Cool!

The big problem is when I turn on both pickups (neck & bridge), the volume is getting low and the sound is thin and ugly.
Any ideas why?

your pickups are out of phase I think.

Yeah your phase got reversed somewhere. Make sure you check the rhythm circuit and everywhere to see if your wires haven't been reversed somewhere.

Thanks guys, I will check it tomorrow.

I believe they're meant to be like that on vintage and AVRIs - the polarity / phase is reversed on neck and bridge so that "both on" is hum cancelling. The MIJ pickups are both the same polarity which is vintage incorrect but I hate the out-of-phase sound too. You just need to swap black and coloured wires on one pickup - but for the pickup you do that to, the claw will need to be soldered to the "new" ground, not the "old" ground.

Thanks for the tips, but I now got new problem :oops: .

The "out of phase" is gone and both pickups do the job but when I use only the bridge pickup the sound is blurry and the volume is low then the neck pickup.

What I do wrong?

Wiring diagram or photos needed!

Sorry - I meant the wiring you did, not the official diagram, since there is clearly a problem.

I believe they're not meant to :wink: ....

If you have both phase and polarity reversed the pickups are twice out of phase putting them back into phase. AFAIK vintage Jags were not supposed to have an out of phase sound when combining the two pickups.

Agree with you on the rest though (including the hate for the out of phase sound)

I've seen the reverse wind / reverse polarity thing mentioned about Jag pickups a few times - e.g. Seymour Duncan's vintage set:

However they may be wrong of course. I put an AVRI bridge pickup in my MIJ Jag and got the out of phase sound, which I will fix when I get some spare time one of these days (along with the backwards claw, I wasn't having a great day when I put that in).

I didn't argue against the intentional use of rw/rp pickups but rather against the notion that they produce an out of phase sound.

If you have one pickup with EITHER reverse wind OR reverse polarity it will give an out of phase sound in combination with the other pickup. However if you have reverse wind AND reverse polarity the combination will put the pickup sonically in phase with the other.

Ah - sorry - I just put both there because I didn't know which it actually was, the slash was meant to indicate either-or.
