I have a GS112 cab, and I useing with my AG500 head. I love this rig, but It's not a lightweight portable rig, but even not a big thundering big stage rig... Just now, there is a very good deal, for a GS115 cab, in my town. So I will try it! Do you have any experience with this cab? Why Aguilar stop manufactureing this cab, was not a successful product?
