The GRGA21 is an RGA series solid body electric guitar model introduced by Ibanez in 2011. It was made in Indonesia as part of the entry-level GIO line and is among the most affordable RGA models offered. It replaced the GRGA11, which is similar except with chrome hardware and uncovered pickups.
The GRGA21 features an archtop double-cutaway basswood body bolted to a maple neck with a 24-fret rosewood fingerboard with dot position markers. Components include dual Ibanez covered humbucking pickups and a fixed bridge.
