Today, I bought this small version HT5 head. I plugged in the first baffle my Class5 a celestion 10. It sounds really good. I took the amp back to also compare the power. The HT5 seems a little less powerful than Marshall, but I am not. Some had doubts about the 12 BH7, but it is very very good job! I then plugged it into my 2x12 celestion greenback, where, fortunately, I have too much hair on the stone, that mind-blowing! The sound is great!
The clean sound is not bad, I did not take that! on the other hand, cranked, it's beautiful!
The second channel, climbing very little gain, it's already a big crunch at the bottom, it rocks! No need to pedal.
I will update after testing it a little more, but hot, but good.
