Upgrades you say? This guitar has had everything. The pickups have been changed for Seymour Duncan Pearly Gates, this required some routing as the uncovered pickups that were in as standard were a little smaller. The electronics have been changed to remove the push/pull pot and I gave it a re-wire. the bridge had been changed for a Gotoh Chrome one and the control knobs swapped to match. The tuners have been swapped for Gotoh Chrome and a bone nut fitted. The nut slot was strange as it wasn’t flat or curved to match the finger board. but lower in the middle, meaning the new nut looked quite odd. Setup with 9 – 42s.
