The cover does it's job, covers my AC30C2 from dust at our rehearsal space. Wouldn't use it though for gigging. It's a quite snug fit and I have to remove power cord and footswitch lead from the amplifier to get the cover on. It has a strong odour, which I hope will eventually go away. Furthermore text "rockbag" is written upside down, which I don't mind it at all. I would have turned the ugly text side to the rear of the amp anyways.
