Scott - going by memory here and not at home where I can check my files, but IIRC Eppi used a 5 string sized jazz pup on the 4 string NR basses. So if you go the Geezer route (which I highly recommend) be sure to double check your Jazz pup size before ordering. Also, the Geezer set that I used came with all the quick connect solderless pots and jack - note - no knobs, and the stock Eppi knobs don’t fit the EMG pots, so plan on some after market set screw equipped knobs (I was generously gifted a cool set by @JIO, pics to follow shortly).
BTW - did I say what a fantastic club this is! Huzzah to our Queen for setting the example for all TB club leaders to follow!
I still need to install that NR bridge and guard you sent me weeks ago. Thanks so much for being part of the club and an active supporter! Love how you and countless others here keep moving the Tbird passion forward on a daily basis. Now if you could just get that roadie guy of yours (Geddy who’s his face) to start contributing here, jeeze, what a slacker he is.
