the idea of a light / portable amp bag to go with my light portable wt300 interests me. any suggestions/ experience with amp bags (as opposed to racks). oh, i am pretty sure EDEN makes one, but i thikn its pretty expensive. looking for affordable here! OR, do they make racks of other than 19" width? perhaps a 13" width rack for the eden? lookin for options & suugestions & experience. thanks!
