I'm considering buying a PRS SE singlecut Trem and am not sure if the PRS tremolo bridge is f spaced or has the same spacing as the stoptail. I have some eric johnson humbuckers that I'd love to put in it if I purchase it but I'd like to make sure they'd work. Thanks!
Honestly, it won't make a huge difference whether it is or is not F-spaced. You may not be in all magnetic fields, but you could raise the pickup a little to compensate.
To answer your question though, I don't belive it is F-spaced.
Its not.

Fender and Floyd bridges have the same string spacing, which is different from other spacings. Fender spec bridges and Floyds need F space pups, and I believe thats all.
