I've got this Gibby and I don't know what pups are in it. It is a recent model(1995) ES-175. The pickups are unmarked except for a Patent Applied For sticker on them. The current models have 57 Classics in them, but earlier ones may have had 490s....any way to tell by looking? I'm sure measuring the resistance would give some insight, but I'd rather not unsolder the pickups in a hollowbody unless I'm going to replace them...
