So I initially bought the "original" Jackson Case Kelly/Warrior case (item number 224864 at Thomman.de) and that case was too tight for my Jackson Kelly - didn't fit. But this one, is very very similar, if not identical to the Jackson's, but the interior is much more spacious. My Kelly guitar is bought around 1995 (+/-, I don't remember the exact year). So my particular model fits nicely into this SKB case and even has some spare room. And no, once the case is closed, no guitar movement is felt. The build quality is usual that of SKB (I'm satisfied). I read other review about this case that the handle is fragile and broke after a flight - well, the handle does seem to be fragile, but since I am just going to use it within a single country and manage it myself, I think all will be fine.
