Hi, I would like to replace the stock pickups on my MIJ Fender Mustang with the Lollar Mustang replacement pickups. Lollar have two different versions of the pickups, version A and version B. A Lollar employee told me that the easiest way to know which version will fit is to measure between the pole pieces, on center. I would have to take the pickup covers off to do that, which shouldn't take longer than a few minutes. Problem is, the wiring is pretty tight between the pickguard and the control panel. I have no experience with installing pickups, so I worry that I will have a hard time re-attaching the pickup springs, and worst case scenario, that I will turn the Mustang into an "acoustic" bass. ;-) So, my question is: Have any of you bought Lollar pickups for this excact model (2010-12 FENDER JAPAN MUSTANG BASS MB-SD/CO OCR COMPETITION STRIPE DUNCAN), and/or know which pickup version (A or B) I need for this bass? Thank you in advance!
