The RGIR30BFE features a mahogany body with multi-binding bolted to a maple and bubinga Nitro Wizard neck with a 24-fret bound rosewood fingerboard. Components include a fixed bridge, dual EMG active humbucking pickups with a kill switch and Gotoh locking tuners. The RGIR30BE is very similar except it has a tremolo bridge. The RGIR37BFE is a similar seven-string model while the RGIR38BFE is an eight-string version. The RGIR20BFE is similar but lacks the multi-binding and Gotoh tuners.
