I dunno, I think it's decent sounding in the clips, but I'd have to try it out first.

Sounds all right, but if it were about $100 cheaper, I'd get it. $799 for a tube amp with effects, with the tube and power section by Bogner? Sounds decent.

I'd have to try one out to be sure. Companies can always tweak the EQ etc of clips to make them sound better.
