I am in a hurry to decide on what head I'm going to buy. I have a show coming up with Origin and it would be a little embarassing to be playing on a peavey 212 combo...Anyway I play brutal death metal (Guttural Secrete, Devourment, Disgorge) My main worry it the distortion cleans dont matter to me...I need good low end with lots of gain...My choices as of right now are the Crate GT3500H (Great LOW end), Spider Line 6 (very wet/gainy distortion)...I'm NOT interested in a tube amp right now so if you have any other suggestions on what head i should get, or even better give details on the two heads of my choice please explain. Thank you.
