The GRG7221 is a seven string RG series solid body electric guitar model introduced by Ibanez for 2013. It is part of the entry-level GIO line. It is the most affordable seven string model Ibanez offers.
The GRG7221 features a poplar body bolted to a maple neck with a 24-fret rosewood fingerboard with white dot position markers. Components include a pair of Ibanez humbucking pickups, a fixed bridge, a plastic nut and Ibanez die-cast tuning machines.
In mid-2017 a new fretboard material, treated New Zealand pine, replaced rosewood. For 2018 the bridge was changed to the F017 in the US, European and Asia; the "fixed bridge" was retained in other markets. For 2019 the F107 bridge was available across all markets. Also in 2019 the 3-way pickup selector was replaced with a 5-way blade switch. For 2020 the fretboard was changed to purpleheart.
