They look identical. I bought a pickup for my 84 Sabre but me and the person who sold it for me are trying to figure out which one of the two pickups he has are the bridge pickup. I was wondering if the pre Ernie ball sabres pickups are interchangeable or identical to one another or if there’s some clue as to which is the bridge pickup and which is the neck pickup, can someone maybe measure magnet spacing or get some readings on the electronics so we can figure this out?!
