This pickup is a humbucker that will fit under a P-90 cover. I call it a F-90 because it is actually constructed the same as a Gretsch Filtertron with some minor alterations to hide it under a P-90 cover.
Why do this you may ask…? Most of my intrust and experience is in Vintage Restorations, and I have a customer who wanted a humbucking pickup for recording that will cancel the hum, but not alter the appearance or require any alteration on the instrument.
BTW: Besides keeping its vintage appearence, it Sounds Awesome!
The center row of pole pieces are just for appearence as you see they are screwed in to a nylon spacer. The working pole pieces are the 2 outside rows
Faux pole pieces show through the cover.
