The RG550 is an RG series solid body electric guitar model reissued by Ibanez in late 2017. This model is a reissue of the original RG550, which was produced between 1987 and 1994.

Similarities to the classic RG550 include a basswood body, a tilt neck joint with a stamped metal plate, a maple fingerboard with dot position markers and an original Edge double locking tremolo bridge with a locking nut. Differences include a five-piece laminated maple and walnut neck and the pickups which are a pair of Ibanez V7/V8 humbuckers flanking an S1 single-coil.
