Here is the description; This case is a convenient, protective housing solution for MarkBass' Little Mark II, Little Mark 250, and LMK amp heads. It includes comfortable shoulder strap, carrying handle, and a handy pouch for extras like cables, charts, tuners, etc. The amp can even stay in the bag during use. I had it for a GK MB500, but never needed to take it anywhere and just sold the amp and got a big 'ol Eden, so I'm not gonna need this. It fit the GK perfectly and probably works for many small amps. It is $60 new everywhere, how about you send me $30, and I ship it anywhere in the contiguous 48.
