p90 types

[telemonster]

hi,

just bought a pair of 'duncan designed' p90 types (stacked?) with 4 conductor wire. now, i've been on the site and looked at what i thought was the right diagram-however, the wiring is kind of the opposite to the diagram. that is to say, on the diagram, red and white are soldered together, and the green and black are earth and hot. on these p/ups, the red and white are 'out', suggesting they are earth and hot, and the other 2 wires (i guess black and green) are taped up!
what to do, guys? wire up as is, or follow the diagram on the website.

by the way, they came out of a squier tele custom type.

thanks,

paul

Re: p90 types

I think Duncans humbuckers without a coil split are always:

Tape RED and WHITE together.

BLACK and BARE get grounded together.

GREEN goes to pot or switch.

Feel free to correct me if I'm wrong...

Re: p90 types

Would have to check the site for that particular p90, but SDs are usually red-white together as mentioned, but GREEN AND BARE go to ground and black is hot- Of course duncan design could be different-

Re: p90 types

It is red and white together Green and bare grouns and Black out put. I guess you bought the pick up used?

Re: p90 types

So if I have been putting the GREEN as hot instead of BLACK(RED and WHITE together and taped off, BARE and BLACK grounded together), what kind of sound is actually coming out of the Humbucker?

Re: p90 types

hi,
thanks for your replies...
i bought them used off ebay-they were in a squier custom tele before. i haven't wired them up yet as i have had some experience of sd's before and knew the red and white usually went together. so i looked at the diagram on the site which confirmed what i thought. i can't understand why these are wired differently. it's a puzzle. i might just wire them up as per the diagram.. that should be alright!

Re: p90 types

oh god, i'm so stupid!
i've had a closer look, and here's how the wiring looks: red/white/bare. bare stuff was taped up, and the red and white were 'out'. i now believe them to be p90-2's-that's what the squier site says! however, there's no diagram for p90-2's on the duncan site....i guess i can make either red or white hot, and the other earth? the bare stuff, i'll tape back together?

now clear that you have single coils not the stacked 4 conductor- But still unclear what you have- The p902 is a single conductor (ground and negitive are common and separate hot wire-)

If they are true 2 conductors, as you said, you should be able to choose red or white hot and as long as you keep it on both pups you should be in phase and all ok- Bare goes to ground-

LEt us know how they sound!

Unless this is an unusual SD, you are wired exactly reversed from a regular humb- So problem would be if you combine with a humb that is regular wired- they would be phase reversed and you would get a thin brightish sound when you somine them- Of course if the other humbecuker was wired backwords as well, you wouldn't have any sound problems-

The humbucker sound should be the same, you're just reversing the current. The problems come in when you use it with other pickups because it will probably be out of phase with them, which will give you a very hollow, weak, nasal tone.

But it's easily fixed -- just reverse the black and green wires.

Re: p90 types

Well guys, I wired the other humbucker just the same, so that's probably why I haven't noticed a thin weak sound

I think my problem is that I wired RED and WHITE together and went to the toggle switch, and from there it goes right into the tone pot.

If I understand correctly, RED and WhITE are wires together and put on a switch ,that when activated, grounds RED and WHITE, then send the single coil sound through the Black wire.

I still seem to be getting a coil split though....

Interesting.... The Squier site says P90-2s and the Duncan site, on the Duncan Designed page mentions p90-1s but not P90-2s...
