Hoffee cases look interesting. I got in touch with him to see if he'd make one for a shorty bass, but he was reluctant as he isn't making bass cases yet and didn't think it would fit in a current shell. They say custom made, but I think he's only capable of making the sizes he's created molds for and the actual custom work is in the interior.
Some of the other case manufacturers I've spoken to have expressed skepticism that a carbon fiber case can be made so cheaply, but from all appearances, they look pretty good. I'd love to see one in person. Maybe by the time my bass is done, he'll do a bass case.
