I'm kidding man. I'm just really tired lol. I can't help ya, but I'm pretty sure you're right. They're phase out. Could be wrong though.

Re: Just a little P90 quest.
Depends on the company. Different peeps wire them differently.
Most put them in-phase, but it's possible to find them out of phase. Can't think of an out of phase company off hand, but they are out there. Reverend? PRS maybe?
Anyway - it can happen.

Re: Just a little P90 quest.
My guitar is Godin LG. There were two Seymour Duncan SP90 pickups. They were out of phase primarily. Then I've changed everything except neck pickup and bought Antiquity P90 for bridge position.
Neck SP90 has two wires (one black and one white), Antique has two wires aswell but of the same color. They are out of phase now, that's why I upgraded guitar with phase switch. But there is a grounding issue when I switch in normal mode and thats why I'm interesting if out of phase is NORMAL mode for P90 pickups or not.
Anyway, now I think it doesn't matter because I've got no idea where to get those two conductor+ground wires))

MY PRS has a RWRP neck compared to the bridge. There is no hum in the middle position.

Re: Just a little P90 quest.
When two pickups that are out of phase with each other are combined so that both are on the resulting tone will be thinner and more nasal than the tone of either pickup used by itself. Is that what you are experiencing? If so, your pickups are out of phase relative to each other.
Two Antiquity P90's or two Duncan P90's of the same model should not be thin and nasal sounding when combined but if you combine a neck and bridge model they should be humcancelling when combined. That's because the bridge model will be wound to be reverse polarity and also reverse wound compared to the neck model.
If you had a P90 was just reverse wound or just reverse polarity compared to the other pickup the resulting tone when both were combined would be that thin nasal "out of phase" tone.
But by reverse winding one pickup and also reversing the magnets so the polarity is also reversed they should NOT sound thin and nasal when combined.

Re: Just a little P90 quest.
Correct me if im wrong but Lew is suggesting to flip the magnets to the opposite polarity so you get the hum canceling and in-phase

Re: Just a little P90 quest.
When two SP90 were installed the tone was that thin. Out of phase. I thought it was depending on special wiring combination on the switch, now I think it's not because I've changed switch to Dimarzio's one.
Now, when antique is new bridge pup, if I remove phase switch and leave them way they're supposed to be wired they will sound that thin aswell. Out of phase.
I didn't get Lew's idea of changing magnet's polarity aswell so:

Re: Just a little P90 quest.
Hi Lew, just off topic a bit, but assuming what you say is correct, that one of the Vintage P90's or Antiq's is reversed, what if I want to stick a Dimarzio that is rw/rp in the middle....will i get hum cancelling in only one of the 2 or 4 positions....and the same effect if it's NOT reverse, just hum on the opposite combo? Whew~~

Re: Just a little P90 quest.
Hi Lew, Do pairs of SD Vintage P90's & Antiquities pairs for neck & bridge automatically come with one of them rw/rp? And if so, if i put a rw/rp middle from Dimarzio, will only one of the 2 or 4 positions be hum cancelling, and if i put a non rw/rp in there, would the opposite position be hum cancelling? Thanks, kenny
