The RBM1 is a Reb Beach series solid body electric guitar model introduced by Ibanez in 1991. It is a signature model of American guitarist Reb Beach, who is best known for his work in the melodic rock band Winger. The RBM1 was made in Japan by FujiGen.
The RBM body style is the second unique body shape used by Beach after the modified Explorer styled WRB3 model. The body, which was designed by Reb Beach himself, features a deep cutaway at the back of the body all the way to the tremolo. It is also known as Voyager style.
The RBM1 features a mahogany body bolted to a maple neck with a 22-fret rosewood fingerboard with pearloid dot position markers. Components include Ibanez pickups with a humbucker at the bridge and single coil-sized humbuckers in the middle and neck positions and a double locking tremolo bridge. The RBM1 was introduced with an Edge tremolo and no pickguard. For 1992 a brass pickguard was added and the trem was changed to the Lo Pro Edge. For 1993 the Ultra neck profile was adopted.
The RBM2 is a more deluxe version with an Hawaiian koa top, Bolivian rosewood neck and fretboard and EMG pickups. The RBM1S is a version with EMG pickups which was offered only in Japan.
The RBM1 was discontinued after 1993. It was replaced by the RBM100 and the more affordable RBM10.
