Thanks for the replies. Yes indeed it is difficult finding something appropriate. I can get a case from Gibson for the princely sum of £259, against the Gator iat £170! Can't see any pre owned for sale at the moment.
I got into short scale basses about five years ago after a tendon issue affected my playing. Since then I've started to love playing short scales and have a Supro Huntington, Sandberg Lionel and the Gibson SG. I fully agree with your views re Gibson design and build, but then again I do love the sound and playability of the SG Bass especially with a set of Ernie Ball Cobalt Flatwound Super Slinky 45-100 strings. I bought the Gibson pre used, hence the rectangular case, as I would have preferred the shaped case.
Cheers
