The GRX150 is an RX series solid body electric guitar model offered by Ibanez. It was made in China as part of the entry-level GIO line. This version was introduced for 2021 with several changes from the previous model.
The GRX150 features a basswood body bolted to a maple neck with a 22-fret rosewood fingerboard with white dot position markers. Components include Ibanez Infinity R pickups mounted in a black pearloid pickguard with a pair of humbuckers flanking a single-coil, an Ibanez FAT-6 synchronized tremolo bridge, and Ibanez die-cast tuning machines.
The GRX6SP1 is a similar model with an art grain ripple maple veneer top and no pickguard.
