I had a svt2 & 4, I found the 4 to be a great amp a bit underpowered compared to the rating, The Svt2 was the worst valve amp I owned so heavy and uninspiring compared to my 400+ and my old V6, StraightSix has a V6 up for sale you will not believe the tone that baby puts out into the Barefaced cab he has, Pure bliss and he's a great guy to deal with.
