One with a small scuff at the bottom (older style cab) and the other is the newer one wider cab.
I will ship coast to coast in the 48 but the buyer must pay shipping.
The older cab is taller and narrower. They both weigh about the same - in the 30ish range. Honestly, they sound pretty much the same. A very plump, oldschool sound but good higher range when its called for. Both are very well constructed.
