Does anyone out there know of any online guides or listings of older alembic pickups? I just picked up a used steinberger XP2 not one of those new spirit monstrosities, but one of the old vintage 80's ones (they look much the same, a sort of flying wing) Anyway it has some similar era pickups in it that have Alembic engraved into the pickup itself (not the gold lettering, but deeply engraved grooves) and I'm kinda curious to find out more info on them. Google has let me down, can anyone here suggest a place to look? If it helps I can get some pics of them online . . .
