The GRX50 is an RX series solid body electric guitar model introduced by Ibanez in late 2014. It is made in China as part of the entry-level GIO line.
The GRX50 features a poplar body bolted to a maple neck with a 22-fret rosewood fingerboard with white dot position markers. Components include Ibanez Infinity R pickups with a pair of humbuckers flanking a single-coil mounted in a pickguard, a synchronized tremolo bridge and chrome hardware.
For 2018 the rosewood fretboard was replaced with treated New Zealand pine.
