Hi all,
I recently aqcuired a 70s Precision which has (I think) a DiMarzio Ultra Jazz fitted at the bridge. Each pickup sounds fine individually, but having them both on full makes the E and A strings sound out of phase. D&G both sound as expected, so I'm assuming one half of the P pickup is out of phase with the J pickup.
I've currently got it wired VVT. One weird thing is the out of phase effect is strongest when I have the Jazz on full and the P at about 95% - still only on the E&A with the D&G unaffected.
I've got another P with an added J pickup that doesn't have these issues - any ideas?
Cheers
