The RG2228M is an eight-string RG series solid body electric guitar model introduced by Ibanez in 2013. It is part of the high-end Prestige line.
The RG2228M features a basswood body bolted to a titanium reinforced maple and wenge 27-inch scale Ultra neck with a 24-fret maple findgerboard with dot position markers. Components include active EMG pickups, a fixed Edge III-8 bridge, a locking nut and Gotoh tuners.
The RG2228M is essentially a twin of the RG2228, but with a maple fretboard. The M variant was available only for 2013.
