The RG4EXQM1 features a basswood body with a quilted maple top and a white binding bolted to a maple Wizard II neck with a color-matched headstock and a 24-fret bound rosewood fingerboard with sharktooth position markers. Components include Ibanez Infinity pickups, an Edge III double locking tremolo bridge and a locking nut. The RG370DX is a similar model without the exotic top. The RG4EX1 is essentially the same guitar which was sold in 2006 and 2007. The RG4EXQM1 was discontinued after 2011.
