Steve Vai's Funky Sitar

The end of Boy from Seattle has a cool effect in it. He makes a Sitar-type sound by bending ta note on the B string many steps up, enough to pull it off the fretboard on on the side of the neck. Then vibrato-bend the string so it repeatedly goes on and off the edge of the neck. The rapid rise and fall of the pitch gives it a sitar-like quality.

This is hard to explain via tab, so one is not included.
