The cost of the pro case, which you have and the SKB is virtually the same. £130. If you want to protect your bass, my advice would be, a decent flight case. For a few pounds more you can have something built that is bomb proof, protects the neck and you can padlock if you need to.
I'm a bit anally retentive I know, but all my 60s Fenders go in a flight case. I don't like the cases supplied with guitars but I know a lot of people do. That said, you should have been supplied with the case you were expecting.
Funnily enough, when I bought my first G&L 6 string, I thought the hard case was great, until a few people told me that Hiscox make something better for £99!
