I've seen his acoustic live sets, and I have to disagree. When he gets really fast his alternate picking breaks down and it mixes between legato. Not only that, but the licks he plays at those speeds almost sound like they are just 'stock fast licks.' Some of the notes and whatnot don't really go with the underlying progression, maybe that's due to his heavy EVH influence.
Listen to the solo on Stillborn to hear what I'm talking about.
Not to say that Zakk Wylde can't play, but I wouldn't call him a virtuoso.
Back In Black isn't a song. It's a divine call that gets channeled through five righteous dudes every thousand years or so. That's why dragons and sea monsters don't exist anymore.
