DiMarzio FAQ
Q. F-spaced?- what the er… heck ?
A. To determine whether you need F or non F-spaced pickups measure the strings E-e over your neck and bridge pickups, if your measurement is closer to 51mm then you need F-spaced, if your measurement is closer to 48mm then non F-spaced are for you and remember, if in doubt – ask !
