So I found a deal on a second GB 8T so I figured I would pick it up to have when I needed a bit more power and volume. When I add the second cab there is a significant loss in the low end and volume decreases as well. I assume this is not normal and the opposite should be happening. Each cab by itself sounds great, but together, YUCK. I have always been a combo or 1 cab and head player. So am I missing something here? FYI: please move to the Amps section.
