The JEM series is a line of solid body six-string electric guitar models manufactured for Hoshino Gakki and sold under the Ibanez brand. It is a signature series of American guitarist Steve Vai. The initial model in the line, the JEM777, was introduced in 1987.
The design of the JEM series was influenced by the Fender Stratocaster, but with a more aggressive style. This type of guitar would come to be known as a "super Strat". Perhaps the most instantly recognizable feature of the JEM models is the monkey grip on the upper body.
