I bought this cover for my Orange 212 Open Back.
The finish, quality and cushion on it is simply superb. MUCH finer stuff then the original Marshall one I have on my Marshall gear.
It has openings on the side to get to the side handles, and the stitching is very nice.
Down side is that it is huuuuge. I think it was made for 212 Orange CLOSED BACK cabinets instead, which are wider as far as I know.
So you will have some extra space there, so it will not look snug and tight on an OB 212.
