Hey there mate, Sorry about the delay, hadn't had steam installed for a long long time... This amp is Efficient, Badass and really Versatile. The Price is low, you dont have to spend much on tubes and it sounds close to what an All-valve would.

I recommend a better cab tho, the AVT412A like I currently have, doesn't really hold up on gigs, buy a 1960A or something.

The Head is really worth it, check it out on youtube.
