I have been on a real pickup frenzy here lately and have educated myself well thanks to this forum, at least on Duncan pickups. I want to know what magnet types some of my Gibson humbuckers have so I can draw some comparisons with Duncans. I have an ES-335 with '57 classics. What magnet type are those? How about other Gibson humbuckers that would have come in a Les Paul in the 1980's ? Bottom line is I know plenty about Duncan pickups and not squat about my Gibson pickups! Thanks
