Steve Vai

Steve Vai's relationship with Ibanez produced the JEM — a guitar so specific in its requirements that it included a monkey grip handle, a disappearing pyramid inlay pattern, and a seven-string variant that fundamentally changed heavy music. Vai transcribed Frank Zappa compositions from tape, played with David Lee Roth and Whitesnake, and released Passion and Warfare in 1990 — a record that remains the most technically ambitious guitar album of its era. His use of the Eventide H3000 and DigiTech Whammy for pitch manipulation became so influential that both devices are now considered standard tools. He approaches gear with the same compositional precision he brings to music.
