You may have to settle for a gig bag. Not the end of the world, though. There are some pretty nice ones out there these days. If you'd rather a hardshell, just get a standard Strat case and add some foam in strategic places to keep the thing from swimming around during transport.
That's what I'm going to have to do with the L5S in my sig below. Cases for that essentially don't exist unless you wanna pay a bajillion dollars for a custom made unit, so I'll have to get an ES-series case and add some padding.
