The GRGM21L is a left-handed RG series compact solid body electric guitar model introduced by Ibanez in 2011. It is produced in China as part of the entry-level GIO line.

The GRGM21L 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.[1] For 2018 the bridge was identified as the F106. For 2019 the fretboard material was changed to Jatoba, the body was once again basswood and the 3-way lever pickup selector was replaced with a 5-way.

Like its right-handed counterpart, the GRGM21, the GRGM21L features a smaller body and a 22.2 inch scale length neck instead of the more standard 24¾" to 25½" scale.
