Let me say that I have been a musician for 20 years, and a Guitarist for 16 of them. I have never received such amazing service at every step. Derek, at Sweetwater, has been extremely helpful in making sure my order was hassle-free.
On to this beast of an amp:
LOUD. This is my first impression. You might scoff at a 36w 1x12 combo of you play death metal and black metal, but think again, because this thing can rattle your windows on 5w mode. That's another great feature on this amp, the power soak function, which allows you push the power section harder, without killing your neighborhood.
I've only had it a day, but it already has me hooked on the Hughes and Kettner line. If you are like me, and love the sound of Diezel, ENGL, and Bogner, but don't quite have the 4k to drop, give this amp a shot. Hearing is Believing.
