I've come to the realization that I love big tube heads. However, I hate hauling a heavy large cab. I love my Genzler MG212T, and I don't see it going anywhere. With that being said, it's only 18" wide, and most big tube amp heads are 24"-30" wide. The rubber feet on the bottom of the head wouldn't even rest on top of the cabinet, and I'm worried the vibrations could damage the tubes. What are some ways you all stack a big head on a little cab? Or just set it beside the cab?
