The Ibanez RG is a series of electric guitars produced by Hoshino Gakki and one of the best-selling superstrat-style guitars ever made. The first model in the series, the RG550, was originally released in 1987 and advertised as part of the Roadstar series. That series was renamed "RG" in 1992 and all models since are simply known as RGs.
It rose in popularity throughout the 1980s and had the features that musicians in the rising shred and thrash metal movements of that time were looking for: a fast neck, comfortable body, powerful pickups, and a reliable tremolo system.
The RG series has the most subtypes of any Ibanez model and is the most popular series of Ibanez electric guitars produced by Hoshino Gakki. The RG's deep cutaway, flatter fingerboard and extended fret range (24 frets as standard) has made it one of the most popular guitars for rock and heavy metal music.
