Just wondering what you guys think. I have ordered the head with an ETA of late next week. They do have a combo in stock to ship immediatly. My current amp is running through a Genz Benz Black Pearl 2x12 cab with red fangs.(british voiced eminance) I have always had combos until now and like the open back sound. Anyway, what do you guys think? Why do you prefer one over the other?
