Steve Vai - The Flight Of The Butterfly guitar tab
I think i have stumbled upon how this song is played, or at least how to get it sounding similar.
This is very fast and Steve Vai has adapted it from a classical piece (same name)
I think he picks the song but, if u want the same sound but arewnt able to move that fast (like me :D)
Then just slide your pick up and down the B-string. This gives the same effect with some distort if u make sure u press down on the fret board with the side of the pick.
This is not perfect but there are no other tabs for it so this is a start. :D
