The GRX20EXB is an RX series solid body electric guitar model introduced by Ibanez in late 2019. It is produced in China as part of the entry-level GIO line.
The GRX20EXB features a poplar body bolted to a maple neck with a 22-fret jatoba fretboard with white dot position markers. Components include a pair of Ibanez Infinity R humbucking pickups mounted in a black pickguard, and a six-screw synchronized tremolo bridge and plastic nut.
Some models are produced with Jatoba fingerboard as it shown on the photo, meanwhile some of them are produced with "Treated New Zealand Pine" fingerboard (which is closer to a "Rosewood" fingerboard) same as 2019 GRX20's.
The GRX20 is a similar model with chrome hardware. The GRX22EX is a related model without the pickguard and with chrome hardware.
