The speed that Zakk can play with is insane, and he's not playing legato.

What I hate about videos like this is they feel more like "look what I can do, I'm awesome". In this one he shows you something simple with phrasing. Then he says" once you get it up to speed, it will sound something like this..." and off he goes. The entire subject of how you get it up to that speed is skipped. Like it's insignificant and you can get it down in a few days or something.

And that's the crux of his sound, the speed.

And Axe, you're right about that move by Ozzie - pulling his hair was a complete a$$hole menouvre!
