I've been disappointed when I found that none of 
'Black Star' tablatures doesn't play this part correctly.
It's not even hard, if you use pacemaker for Winamp.

This solo needs to be played by rotating the 
volume-pot (from 0% to 100%) with your little finger on 
EVERY note.
If you think that it's impossible to do with this speed, 
than you should buy one of the Yngwie's 
teaching-CD-s and see it alive.

The alternative is to use some guitar-processor that 
have this effect. (Zoom 505II:)
