Ibanez JEM is an
electric guitar manufactured by
Ibanez, which was first produced in 1987. The guitar's most notable user is its co-designer,
Steve Vai. As of 2006, there are five sub-models of the Ibanez JEM, which are the JEM7, JEM77, JEM777, JEM555 and the Universe. Although the Ibanez JEM series is a
signature series guitar, Ibanez mass-produces several of the guitar's sub-models.
The Ibanez JEM series is heavily influenced by the superstrat concept, which is about a more aggressive guitar in terms of shape and specifications compared to the Stratocaster. Moreover, in the production process, Ibanez and Steve Vai compared the specifications of the Stratocaster, Ibanez RG and Steve's older guitars.
