I have all the original parts and pickups, but the following work has been done:
Upgraded pickups to Fender Lace Sensor (Blue) in the Neck.
Seymour Duncan humbucker in the bridge.
Rewired switches to: Neck switch selects neck/parallel/bridge pickup. Bridge switch splits the humbucker, Humbucker/Split/Parallel wiring.
Pots were upgraded a few years ago. Still 250k.
