I couldn't find a suitable case for my Ibanez Artcore AGBV 200. It is semi acoustic, so quite wide, and short scale.
Bought some 3.6 ply, and some 95 x 12 pine and some 44 x 12 pine. I got this from a local timber merchant, but it's still bent and twisted, as you can see from the photos. I can't straighten it, so used the best bits and will sand off the worst bits at the end.
Drew around the bass, allowing for adding some foam. I had to plane down the 95 to 62 so the case wasn't too deep. Cut the ply, stuck on the sides to make the bottom half.
