The RBM1S 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 RBM1S 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 RBM1S features a mahogany body bolted to a maple neck with a 22-fret rosewood fingerboard with pearloid dot position markers. Components include EMG active pickups with a humbucker at the bridge and single coils in the middle and neck positions and an Edge double locking tremolo bridge.
The RBM1 is a similar model with Ibanez pickups. The RBM2 is a more deluxe version with an Hawaiian koa top and Bolivian rosewood neck and fretboard.
