Information on Seymour Duncan STK-P1 hum cancelling P90 pickup

[Charvel1975]

Hey got some questions regarding the Seymour Duncan STK-P1 soapbar P90 pickup? I saw a used one for sale and seeing as how my 1998 Gibson les paul special came from the factory with
P-100's I'm assuming this would fit in the bridge of my les paul special correct? Now they didn't specify if this was a bridge or neck model? All they had in the description of it is that it has Alnico 5 magnets, Stacked hum cancelling design. Marked "IKT47-STK" on label, and they said this may be an OEM number as it was removed from a Gibson Double Cut Special?

The Seymour Duncan P-90 is OEM for a Gibson LP Special?!

It might be now. My old LP Junior Special came with P100s, the necessary deeper cavities and longer height adjustment screws. The SD Stacks will retrofit directly.

A DC resistance meter reading will identify which version you have.

I don't recall ever selling STK-P1 pickups to Gibson.

I have an STK-P1 N/B pair. Each pickup has a sticker on its baseplate. Each sticker carries a model ID, a four figure number and the same three letters + two digits code that you identified.

On your pickup, the model ID number should read STK, followed by a number (1) and a letter (N or B).

I just found the stock Gibson bridge pickup and measured the height and it's a little under 1 inch which leads me to believe it's definitely a P100. I know on the SD site it says the STK-P1 bridge model's DC Resistance is 15.84 k and the resonant peak is 3 KHz but I was also looking at a used SD Hot P-90 Soapbar for the bridge and the DC Resistance is 14.9 k and the resonant peak is 4.7 KHz. Right now I have a Dimarzio super distortion p90 in the bridge and the factory Gibson p100 in the neck, 300k Gibson pots swapped out some years ago for Gibson 500k pots. I'm wanting to go back to drop B tuning

I suggest that you test the tuning change idea before you change the pickup(s). There is a very strong possibility that the Super Distortion will do what you require.

The overwound single coil P90 idea only really makes sense if you stick with standard tuning. My own taste is for the SP90-3n in the bridge position.

Yea I haven't really played it in a while but right now my LP Special is in 1/2 step E tuning 10-46 gauge strings, factory Gibson saddles swapped out with Graphtec graphite string saver saddles pre-notched, factory Gibson 300k pots changed out to Gibson 500k pots. Before I bought the Graphtec saddles I had it tuned to drop B with the ghs zakk wylde set 10-60's but it just didn't sound right, not enough clarity, oomph, chugs, etc so after I bought the Graphtec string saver saddles to replace the original factory ones I had my tech install them and set it back up to half step E tuning but it still didn't sound right, I think for one he set the action too low or something because the guitar just sounded really twangy, I have a pretty heavy right hand attack but even when I lightened up my attack trying to play Metallica for example it still sounded all twangy and not full sounding and this was plugged into my Mesa Tremoverb or my Peavey 6505+ head??!! And then I started having issues with the factory Gibson deluxe tuning keys coming loose changing strings, etc. So not long ago I bought a brand new set of Chrome Grover 135N Die-Cast Vintage 14:1 Ratio tuners. Hole Size: .391 = 25/64


Should I try installing these new Grover tuners myself and maybe try this set of D'Addairo EXL117 Nickel Wound, Medium Top/Extra-Heavy Bottom, 11-56 strings I have lying around tuned to drop B?
