Great guitar tones, and pretty well mixed, too! Drums are nice and punchy!
It sounds very "studio" which is fine indeed, but I wonder if you dropped in a file of something like "club ambience" it might give it a slightly less perfect/clinical feel, and it would more match the balls-out blues fest you have going here. Justa thought.
You guys clearly know what you are doing.
