Someone said the Engl Fireball before, and I gotta agree. The Fireball is probably the most badass sounding amp you'll ever hear in your life.
Anyone said the Line 6 Vetta 2 yet? I have a Vetta 1, and it's got some of the best tones I've heard in my entire life. My distortion models that I use are the Engl Powerball model for my rhythm sections and the Bogner Uberschall model for my leads and solos. It sounds faptastic.
