My favorite P-90 pickups are are the Fleor.... I dare you to search for them..... be shocked by the price.... not even sure if they are still made.. the ones available and that I have received look to be old stock by the packaging.
Yikes! I just looked up how much a set of those pickups are!
they should fit at that price.
are the base plates in the way or just the plastic corners?
I’d maybe heat or file the corners.
I have the 18 special too, and while the minis read hot, I didn’t find them particularly offensive…...
