Are we talking actual Death Metal (Autopsy, Entombed, Immolation, that sort) or modern "Death Metal" which you young'ins mistakenly call it these days?
If we're talking Death Metal, I am as staunch an advocate of the War Pig as you'll ever find. I have a '97 SG-I with a C-pig in it and I love it to bits. The thing is absolutely monstrous!
