The AR50 features an arched maple top on a double-cutaway mahogany body mated to a set-in three-piece maple neck with a 22-fret rosewood fingerboard with binding and pearloid dot position markers. Components include dual Ibanez Super 70 humbucking pickups with creme bobbins and no covers mounted in cream pickup rings with individual volume and tone controls, a Gibraltar Tune-O-Matic style bridge and Quik Change tailpiece, rubberized Sure Grip control knobs and VelveTune machine heads.
Some AR50s produced in 1979 had 24-fret fingerboards; most have 22 frets. Cream body binding was added sometime in mid-1980. For 1981 the neck was changed to birch only to be changed back to maple for 1982.
The AR50 (Jr. Series) was this model's immediate predecessor. It was produced in early 1979 with the pickup selector relocated from the upper horn to a location near the volume and tone knobs. This was done to simplify production to allow the guitar to be sold at a lower price. The AR30, introduced in 1982, took a similar approach although the control layout is slightly different on that model.
The AR100 is a similar model with gold hardware among other changes.
