[VIDEO]http://www.youtube.com/watch?v=5bKIxrCa8Tg]YouTube - ‪Steve Vai with the Zoom Q3HD‬‏[/VIDEO]
The Zoom thing is the video recorder.
Good god I love Vai's playing so much. He has a fluency and finger tone that no other guitarist I've heard has to the same degree, you really can tell he has sat for several years'-worth of hours just practising getting every conceivable sound out of his instrument.
Killer tone in this clip too. Wonder whether it's all Axe-FX or whether it's just providing effects.
