The GRX20DX is an RX series solid body electric guitar model introduced by Ibanez in mid 2011. It was produced in China as part of the affordable GIO line.
The GRX20DX was a spot model which never appeared in a catalog. It may have been sold exclusively by US retailers Guitar Center and Musician's Friend.
The GRX20DX features basswood body bolted to a maple neck with a 22-fret rosewood fingerboard with sharktooth position markers. Components include a FAT-6 non-locking synchronized tremolo bridge and a pair of Ibanez Powersound humbucking pickups mounted in a black pickguard.
The GRX20 is a similar model with standard dot fretboard inlays. The GRX70DX is a related model without the pickguard and with a middle single-coil pickup.
