The RS300 features a solid ash double cutaway mahogany body with radiused edges bolted to a rock maple neck with a 21-fret maple fingerboard with black dot position markers. Components include a trio of Ibanez Super Tap 6 single coil pickups mounted in pickup rings with the bridge pickup askew, a coil tap toggle, an Accu-Cast fixed bridge with a sustain block, a brass nut, Sure Grip control knobs and VelveTune Mini II tuning machines. Strings can be either routed through the body or terminated at the bridge's integrated tailpiece. The output is mounted on the face of the guitar. The Quadra-Lock neck joint uses four metric machine bolts mounted into threaded inserts in the neck.
The RS300L is a left-handed version. The RS100 is a similar model with a curly maple top on a mahogany body and no coil tapping functionality. The RS500 is a related model with neck-through-body construction and a phase switch.
