It was an early model in what would come to be known as the S series. The series is distinguished by the sleek double cutaway body shape which is arched on the top and back resulting in a fairly light guitar with thin edges.
The 540S-HH features a mahogany body bolted to a maple Wizard neck with a 22-fret rosewood fretboard with dot position markers. It uses IBZ/USA pickups made by DiMarzio with dual humbuckers mounted in pickup rings at the bridge and neck positions. Components include a double locking tremolo bridge with a locking nut and Gotoh tuning machines.
The 540S-HH has a traditional bolt-on neck joint with a stamped metal plate.
The 540S is a similar model with a humbucker/ single-coil/ single-coil pickup arrangement.
The 540S-HH was discontinued after 1989.
