The RG120 is one of only a few RG models produced with a 22-fret neck. It has the rounded-edged body style which distinguishes it from the more sharp-edged modern RG body. The RG120 features a basswood body bolted to a maple neck with a 22-fret rosewood fingerboard with dot position markers. Components include dual pickguard-mounted Ibanez humbucking pickups with Duo Sound coil-tap functionality and a Powerocker tremolo bridge. The RG110 is a similar model with only a single pickup. The RG120 was discontinued after 1987.
