The S 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 440SII features a mahogany body bolted to a maple Wizard neck with an angled headstock and a 22-fret rosewood fingerboard with dot position markers. It has an Ibanez humbucking pickup mounted in a pickup ring at the bridge position and Ibanez single-coil pickups in the neck and middle positions. Components include an HQ-J synchronized tremolo bridge and Gotoh locking tuning machines. It has a traditional bolt-on neck joint with a stamped metal plate.
In 1990 the 440SII had Ibanez V2/S1/S1 pickups. These were swapped for V6/S3/S2 pickups for 1991.
