If you're going to be playing that style you may want to look at a brand like Gallien-Krueger. My Ashdown gives a very warm, fat sound that may be better for classic rock than metal.
I've played on several GK rigs and combos, I wasn't too impressed. It felt like I got a better sound out of my laney stuff. I've got a buddy who swears up and down by GK. I'm always hearing "Get GK stuff!!" whenever I talk about getting an amp.
