The GRGM21 is a compact RG-style solid body electric guitar model introduced by Ibanez in 2006. It is the initial entrant in the miKro series guitar line, which features slightly downsized instruments aimed at smaller players. It is produced in China as part of the entry-level GIO line.
The GRGM21 features a solid wood body (see specs for specific species) bolted to a maple neck with a 24-fret fingerboard with sharktooth position markers. Components include dual Ibanez humbucking pickups and a fixed bridge.
In mid-2017 a new fretboard material, treated New Zealand pine, replaced rosewood.
The GRGM21 was also sold in some markets as a set with a special gigbag as the GRGM21GB.
