Gibson P90

Are Gibson still doing their P90's CCW and south polarity ? and they are still not doing a RW/RP ?

I don't have an answer to that... but there's really no reason to reverse wind a pickup... just flip the magnets and wire it up in reverse... like with a humbucker.

I personally reverse wind them etc ,I only have to flip a switch , but I have someone who wants a new bridge pickup for his Dc Jr so I'm going to do the RW/RP for him and am assuming that gibson still use CCW and SP for both pickups , he's in a different state so I can't get my hands on the guitar to have a look , I just want to make sure he gets the correct pickup,

well if you can find out which way his magnet is facing--have him hold a compass up to it--all you really need to do is reverse the magnets. He can flip the wires either way until the two pickups are in phase, and noise canceling.

gibson....

I don't have the details, but I did rewind a Gibson P90 a year or two ago and was rather shocked by what I found. If I remember right they used the outside of the coil for ground for one, the base plate was bent some odd way, was just strange overall, customer liked my rewind way better.....

Last time I checked they were CCW with S Pole to the screws. I'm fairly sure they don't do RW/RP.

They probably do it that way so that the outer winds of the coil act as shielding- as for the baseplate, I have no idea when Gibson stopped using the thick stamped baseplate and started using the cheesy looking brass plate that is either bent, or bends after installation. I'd guess maybe 10 years ago. Also, for some reason, I like the clear bobbins they used to have on the p-90's, I think they're cool lookin'!

[Spence]

The clear perspex are great from the point of view that you can see if your wax potting has penetrated fully.

Ooh...another use for the new mill; making P90 bobbins from perspex.

clear bobbins....

Those were from the 70s and Gibson called them "Laid Back" pickups for some weird reason. P90s were real unpopular mostly in the 70s, you can buy these pretty reasonable on Ebay.....

Yep. I had a set of these from an SG that a guy replaced with humbuckers. I unwound one to 8K to sound like the metal cover dogears I had in my ES-330TD.. made a nice neck pickup. The other one went into a friend's Jazzmaster. I just widened the screw holes and moved the poles wider to match the Fender spacing, and put it in his Jazzmaster pickup cover.

People didn't want the P-90's or the mini humbuckers in the LP Deluxe... Funny how both are popular now.

[TD_Madden]

yes, I have a SD Phatkat I swap in and out of my LP bridge occasionally....just for a P-90 type tone-change...the cover helps with the shielding on that one.

How do you determine CW vs. CCW anyway -- viewed from the top?

I believe so.

Hey Dave, this is interesting. Can you give a bit more info on how you did this and what about the cover too. Cheers. Nic.

Well it's been about 20 years... but from what I remember I took a small round jewelers file and widened the holes in the P-90 bobbin. It was one of the clear plastic bobbins. This allowed me to get the spacing the same as the Jazzmaster pickup. Basically I filed a wider hole, but it was still tight enough to hold the screw. I didn't make the diameter of the hole bigger, I just made it oblong. I probably did the same thing with the keeper bar.

Then I assembled the P-90 bobbin in the Jazzmaster cover. The cover was stock. It looked really slick, with the adjustable poles, and it gave the Jazzmaster a new tone... I installed it in the bridge position. It was just what my friend was looking for. His other guitar was a non-reverse Firebird with P-90's, so he liked that sound. He still got that mellow Jazzmaster tone in the neck position.

It was a really nice candy apple red Jazzmaster.

You can hear it on this track Beat the Clock (my old band from the 80's, the Jetsonz)
