Vai designed the Ibanez JEM guitar, a unique instrument that incorporated a series of groundbreaking designs that have since become staples in feature throughout the guitar industry, in 1985. In speaking of the development of the guitar, Vai says, "Stratocasters had whammy bars—which were fantastic—but they were very limited, were always going out of tune, and had single-coil pickups. Les Pauls had humbuckers—which gave you that real scream in the bridge position—but no whammy bar, and I didn't like the way they sat. Neither guitar had twenty-four frets. So I went to a guitar shop in Hollywood, where I had these elements implemented into a guitar (what would have been considered a Superstrat at the time). The guitar was designed with a sharper body shape, a large cutaway around the neck, twenty-four frets, a fully floating tremolo system, a specially wired five-way pickup selector switch, and an output jack angled on the side of the body (so that when you step on the cable, it doesn't pull out of your guitar). I knew of course that these features would eventually be taken and used in other guitars, so I did something completely preposterous: I said, 'Put a handle in it!' That way, during videos and photoshoots I could swing the guitar around."
