The GRG150B is an RG series solid body electric guitar model introduced by Ibanez in late 2015. It is produced in China as part of the entry-level GIO line.
The GRG150B features a basswood body bolted to a maple neck with a 24-fret fingerboard with white dot position markers. Components include Ibanez Infinity R pickups with a pair of humbuckers flanking a single-coil and a FAT-10 synchronized tremolo bridge. In 2017, the fretboard material was changed from rosewood to treated New Zealand pine.[1] For 2018 the bridge was replaced with the new Ibanez T102 synchronized tremolo and the Chocolate Brown Sunburst finish was replaced by Walnut Sunburst
