A friend of mine bought a '71 in Daphne and it sounds great. My sonic blue Squier Musicmaster ('97) with matching headstock had a special four pole, but it was changed for a six pole. Nice too!!
We discussed it before:
Duesenberg bass humbuckers are six pole, Dano used one type of lipstick for guitar and bass, the new Gibson 335 Bass has a guitar humbucker, the Ricky toaster is for guitars too.
