agj and I have been going through Epiphone's pickups and we're just going through some weirdness. If you want you can join in or you can completely ignore us. I don't know how far this is going to go, or what it's even supposed to do.

Turns out Musiciansfriend doesn't carry a bunch of the ones I had listed. But from that you can see that about half of the Epiphones out there have Alnico Classics for their pups. Better, worse, who knows.
