I just bought a used 1991 GR4 in Black and some one replaced the original
Seymour Duncan pickups with EMG81 in the bridge and S/A S/A in the middle
and neck. I don't like EMG pickups they are (Junk) so now I bought the Seymour
Duncan Humbucker for the neck and Hot Rails for the middle and neck. I just
don't understand why anyone would put EMG's in a GR4.
