I recently had a new wiring harness (wires, orange drop caps, CTS pots and quality pickup selector switch) and bone nut installed. Very pleased with the result. I also have Graph Tech saddles and haven't experienced the rattling bridge problem so I've kept the original. The pickups are stock and sound good to me, but I do wonder what the guitar would sound like with pickups from Fralin, Lollar, Armstrong, etc. The tuners would be the next upgrade if there is one.
