I believe it's the last two digits that identify the year. Makes these a 76 set, but if I'm wrong, someone can correct me. I have a set of date coded, grey bottom Jazz pickups. Last digits 74. What I do know is that out of about a zillion sets of pu's put in my Jazz, the greys are best yet. I bet these P pickups sound incredible. Free bump. An good luck!
It's not WHAT I play, it's THAT I play...
