What exactly do you look for to find these bags or enclosures? Never looked at them before so I'm a bit confused. I'm thinking a bag would be nice just to make everything easier to carry.
I used a general search term of "rack mount flight case 2u"
2u is the height of the front of the amp. Flight cases come in various different heights - 2u, 3u, 6u etc.
Given the depth of the amp from the front bezel to the back plate (around 12-14" iirc) a rack with a depth of 19" is waaaaay too big. It leaves about 5"+ at the front and rear of the amp when the end covers are on, which is great for storage, but overkill imo. (I know, I ordered one by mistake and had to send it back. Lovely case, just far too big).
I went with a 'short' case that is 14.25" from the front to th
e back. Gator GR-2S Moulded Rack Case, 2U, 14.25'' Depth. There's enough room at the back of the amp to store x1 power lead, x1 speakon cabinet lead 2m, x2 1/4" cabinet jack leads 1.5m, without any rattling about or forcing the case closed.
Just about all the ABS racks have x2 carry handles riveted through the side of the box as part of the internal structure and mounting rails. Mine came with hardware to attach the amp to the rails.
The soft cases rely on zips to close off the front and rear of the amp. I didn't like the idea of that. On the plus side they have shoulder straps and stuff like that. But I reckoned the hard-shell case would be better to protect my amp from the elements
I'll try and post some pictures of mine later for you when I'm back home from work.
EDIT: ah, yes... the 'gain' dial. Should be renamed to the thermo-nuclear-boost-o-matic-let-everyone-in-the-street-hear-it knob
