Do u want to know Steve Vai equipment???

Vai is an accomplished studio producer (he owns two: "The Mothership" [1] and "The Harmony Hut" [2]) and his own recordings combine his signature guitar prowess with novel compositions and considerable use of studio and recording effects, such as the Eventide H3000 ultra harmonizer and Digidesign's Pro Tools HD recording system and plug-in effects architecture.

Vai also helped design his signature Ibanez JEM series of guitars. They feature a hand grip (fondly referred to as a "monkey grip") cut into the top of the body of the guitar, a humbucker-single coil-humbucker DiMarzio pickup configuration with several different types of pickup including Evolution, Breed and EVO 2. He also uses Ibanez's Edge locking tremolo system, as well as an elaborate and extensive "Vine of Life" inlay down the neck. Steve also equips many of his guitars with an Ibanez Backstop, a tremolo stabilizer that has been discontinued. Steve also has a 7-string model designed by him named Ibanez Universe. The Universe later influenced the 7-string guitars used by Korn and other bands to create nu-metal sounds in the late 1990s. He also has a signature Ibanez acoustic, the Euphoria. Before he used Ibanez, he briefly endorsed Jackson guitars, but this relationship would only last for two years.

Steve Vai has also worked with Carvin Guitars and Pro Audio to develop the Carvin Legacy line of guitar amplifiers. Vai wanted to create an amp that was unique and equal in sound, versatility, and affordability to any guitar amp he had previously used. Over his long musical career, Steve Vai has used and designed an array of guitars. He even had his DNA put into the swirl paint job on one of his signature JEM guitars, the JEM2KDNA, in the form of his blood. Only 300 of these were ever made. Nowadays he mainly uses his white JEM7V, which is inscribed with the letters "Evo", mainly in order to allow him to distinguish between the guitars he uses onstage which are practically identical, his "Flo" guitar however is equipped with a Fernandes sustainer pick-up in the neck.

He also has a guitar named "Mojo" in which the dot inlays are blue LED lights. Additionally, he has a custom-made triple-neck guitar that has the same basic features as his JEM7V guitars. The top neck is a 12-string guitar, the middle is a 6-string, and the bottom is a 6-string fretless guitar with a Fernandes Sustainer pickup. This guitar was featured on the G3 2003 tour on the piece I Know You're Here. Vai's effects pedals include a modified Boss DS-1, Ibanez Tube Screamer, Morley Bad Horsie, Morley Little Alligator Volume pedal, Digitech Whammy, and an MXR Phase 90. His flight cases are labeled "Mr. Vai", or latterly, "Dr. Vai". He used a number of rack effects units controlled via MIDI, but used a floor-based TC electronics G system instead for the Zappa Plays Zappa tour.
