This case provides military grade protection for your acoustic bass. It's enormous and really quite heavy and once you've opened the six catches you have access to a well lined casket for your axe. You do feel like a magician with all those catches but I guess it ensures you precious cargo doesn't fall out accidentally. There is a very large pocket for strings, straps, capos etc which also supports the neck. I purchased it with a Takamine acoustic bass and it fits perfectly with no movement or unnecessary pressure. I'd have no concerns even checking the case in on a flight - it's that sturdy. If I was to be picky, the lock and key are a bit of a joke but Security isn't an issue for me - if someone is going to steal it, they'll take it case and all. If you gig with an acoustic bass, this is the case for you.
