The GRG121DX is an RG series solid body electric guitar model introduced by Ibanez in 2012. It is as part of the entry-level GIO line.
The GRG121DX features a one-piece maple neck with a 24-fret rosewood fingerboard with sharktooth inlays and two covered humbuckers with a 3-way selector switch. It is a hard-tail model.
