Re: Pearly gates pickup question
SH-P.G.= Standard Spacing or 50 mm's...
TB-P.G.= Tremspaced/F-Spaced/52 mm's
If the sticker has an SH on it then it's a regular old standard spaced humbucker & you will be all set. If the sticker prefix is TB then it's got the wider 52 mm spacing & it's designed for Fender guitars, guitars that are equipped with Floyd Rose Tremolos, Etc....
All Duncan neck humbuckers including the SH-P.G.N. (AKA PEARLY GATES NECK) are standard spaced by default...
