I bought this flight case not for my bass, but for my pedal board.
I was looking for a simple flight case, where I could fit my pedal board for guitar. Cases made for pedal boards are much more expensive. Also the parameters are usually not what I want. I was thinking of custom ordering a case, until I got an idea, that a bass size case would be perfect. I found this cheap case and ordered it without too much thinking because of the low price. While I was waiting for the shipment to arrive I made the pedal board in the size of case's internal dimensions and it fit perfectly.
The padding in this case is really nice and perfect to keep my pedals and your bass safe. However, I did not try it out with my bass guitar. I cut out the extra padding out with a big sharp knife, so that there is only padding from sides, top and bottom. It wasn't clean job, but good enough for pedal board. The case came with some additional padding strips and interesting and funny fastener, which did not hold too good. -1 in quality.
But everything else is perfect with this case. It is built solid. Everything feels like it is made to last for a long time. Both butterfly catches close this case really tight. The grip is funny looking, but feels nice in my hand and safe to carry the case. The low price for the quality is a surprise. I recommend this case for any use.
