Hey guys, so after months of using this case, I can't tell you how it is. you can carry it as normal case, or as a gigbag (check pic).
The only drawback is that the shell is little longer than standard gig-bag. It's as long as Gruvgear gigbag. Also I talked to people that made it, they said that if I ever change the bass, so it has different shape, that there is no problem of changing the inside of the case, so new bass can fit. But, that's why the shell is longer than some gigbags, you can really put any bass inside.
It's just a really great case.
P.S. and yes I'm doing the modeling...
