Good Value, lightweight.
I bought the case for my Mesa M-2000 amplifier. For that purpose it seems to do very well. The end caps fit snug and will help protect the knobs on the front and back, the 2U sized head fits nicely inside the case and is very secure. I like the rails are mounted and predrilled, I had a Rockbag and while nice the screw mounts slid around, a hassle.
However, this case is just molded plastic and rack rails. There is no other kind of protection in the way of foam, wood or anything else. For something like the 2 space amplifiers (Mesa Carbine, Hartke LH) this is perfect. The amp is fairly rugged on it's own and just needs some bump protection as well as good handles to carry it. For more sensitive equipment in need of a rack case, or for extensive travel, a more protective case could be used.
Very good value, and does what I needed it to do.
