I'm not real good on differences between all of the metal genres, but I thought this was as good a place as any to share my pain.
A few weeks ago, I had a guy come to try a 5150III I was selling on CL. The guy had never used a tube amp before, so I spent some time with him, showing him the basic way the channel switching works and how the gain vs highs vs presence can all effect the clarity etc. I even showed what difference boosting with my Tube Screamer made. He was looking for a Death Metal sound and said he was sure the amp was capable of it, but wasn't quite getting "the sound he heard in his head."
Two days later, he shows back up with his Metal Zone pedal, and goes for the clean channel.
Nailed it.
So you might be looking for any amp with a Metal Zone.
