https://playguitarnotes.com/guitars/ibanez-grx20-review/ The Ibanez GRX20 series is part of Ibanez’s GIO lineup, a range of more affordable guitars. Unlike companies like Fender, Gibson, and ESP, this slightly lower end lineup still proudly carries the parent company logo on the headstock. There’s no confusing who made these guitars, and you won’t have to feel any “lesser” for playing one by any means. At present, Ibanez offers two different GRX20 models: the GRX20Z and GRX20W. Prior models such as the GRX20ZJB and GRX20ZBKN are also still easy to find in stock from many retailers, and each one is easily on par with one another.
