When I'm on stage the savage in me is released. It's like going back to being a cave man. It takes me six hours to come down after a show.

My part in AC/DC is just adding the color on top.

A lot of times you'll hear bands and it's a different sound coming out than what's on stage. Because you can clean it up through a PA and make it sound completely different than what they really sound like.

I honestly believe that you have to be able to play the guitar hard if you want to be able to get the whole spectrum of tones out of it. Since I normally play so hard, when I start picking a bit softer my tone changes completely, and that's really useful sometimes for creating a more laid-back feel.

I'm sick to death of people saying we've made 11 albums that sounds exactly the same, Infact, we've made 12 albums that sound exactly the same.

Once you're on stage you can't go back, even when things go wrong people expect you to stay there and entertain them. When all else fails, you've got to try tap dancing.

I just go where the guitar takes me.
