When Steve Vai teamed up with Ibanez in 1987, little did he realize what a lasting impact his signature model guitar would have. Today, the JEM is an iconic instrument immediately identified with the legendary guitarist. The JEMJR features a double locking tremolo system to hold your guitar in tune, even under aggressive on-stage abuse.
Features
Infinity H-S-H pickups
Ibanez Infinity pickups deliver an accurate and tight sound with excellent dynamics. Even under heavy settings, they do not lose tonal clarity.
Double Locking tremolo
The Double Locking system holds your guitar in tune even under aggressive on-stage abuse.
Monkey Grip
One of JEM's most recognizable features: Steve Vai's signature monkey grip. Crank your amp up, grab that baby and hold on for dear life.
Jatoba Fretboard w/Tree-of-life inlay
Jatoba has a reddish brown color which produces a rich mid range with a crisp high end.
Wizard III Maple neck
