I've got the itch for a tube amp! Obviously the dream machine is an SVT, but lords knows how expensive those are, and the amount of volume needed to overdrive it would probably be to much. I've heard alot of good things about the V4 heads, and i can find some pretty good deals locally on them, but i'm wondering how they are in the volume department when paired with a wall of 10s. For comparisons sake, i'm playing through GK BL600 head and never need the level and master above 12 oclock, and we are a pretty damn loud band. How would the V4 compare? Overdrive is my thing, so i'm not worried about clean tone, cranking it isnt a problem.
