Most of my cases are SKB. One is a custom soft case with hard foam under the outer shell which came with my 6-string bass. I also have a couple of thin gig bags that I never use, and a really nice and thick gig bag for my acoustic bass guitar.

The last case I bought was an ABS Gator that said it fits 335-style guitars. Turned out that wasn't entirely accurate. My Epiphone Dot Studio does indeed "fit" in it, but it definitely wasn't made for it. The section for the body is too deep, so with the top closed, the guitar is held in place only by the neck, with no support behind the body. I layed a rolled up t-shirt in there to fill the gap. It's a really nice case, it just doesn't fit my guitar.
