Hi folks, I wanted some opinion. I just bought a pair of 74' JB pickups in order to restore my 75' bass. They were really cheap and in original condition. The guy claims they were removed from his 74' bass but the bottoms are not the same. I've never seen a set with different bottoms before, but the date is correct and they are indeed a bridge and neck pickup. So that's the question, have you ever seen a bass with such setup as stock pickups? Thanks!
