Sorry if this has been done before (did a search but couldn't find it). But I am looking for a head. And when I play with my school I play over a 70's SVT (Think it's called Blue Line) and it's Awesome!!!!!!! So I think I'll like the VR very much. But before I am buying anything I want to know what is the difference between these two Amps? And how much are they like the ones from the 70's? Any Help? Thanks in advance.
