Steven Siro "Steve" Vai (born June 6, 1960) is an American rock guitarist, songwriter, vocalist and producer. As a guitarist, he is known for its work with Alcatrazz, David Lee Roth, Frank Zappa and Whitesnake as well as for his extensive solo career. As an Ibanez endorser, Steve Vai has multiple signature series products, including the six-string JEM series and seven-string Universe series of electric guitars and the Euphoria series of acoustic guitars.
Steve Vai owns an plays several Ibanez guitars. Currently, he mainly uses a couple of models resembling the JEM7V production model. His current main guitar dubbed "Evo" is an early production model and "Flo" is a Floral JEM77 painted over. Due to extensive wear and tear, Vai's guitars occasionally get parts replaced, such as the tremolo and even the neck.
Most of Steve Vai's stage and studio guitars are stock or made out of stock parts, meaning that they are not specially made for him but come from the regular Ibanez production lines. Some of them do get modified to some extent, such as the installation of a sustainer pickup or a True Temperament fingerboard.
Ibanez also built a couple of custom guitars for Vai, including two heart-shaped triple neck models, another triple neck based on the JEM7V and a double neck resembling the JEM77B.
Steve Vai has also worked with Carvin Guitars to develop the Carvin Legacy line of guitar amplifiers. Vai wanted to create an affordable amp that was unique, and equal in sound and versatility to any guitar amp he had previously used. Vai's effects pedals include a modified Boss DS-1, Ibanez Tube Screamer, Morley Bad Horsie, Ibanez Jemini Twin Distortion Pedal, TC Electronics G-System, Morley Little Alligator Volume pedal, Digitech Whammy, and an MXR Phase 90/Phase 100 on the Passion and Warfare album. He has used a number of rack effects units controlled via MIDI.
