The RG620QM is an RG series solid body electric guitar model introduced by Ibanez in 2002.
The RG620QM features a nato body with a quilted maple top bolted to a maple Ultra neck with a 24-fret rosewood fingerboard with dot position markers. Components include a double locking tremolo bridge, dual Ibanez Vintage humbucking pickups and a locking nut.
The RG620X is a similar model which has piezo pickups and lacks the exotic wood top. The RG621 has a fixed bridge and no exotic top but is otherwise similar.
