These cases are great for when you are walking to gigs, or a rehearsal, which I do twice a week at least. It holds my Yamaha YAS-875, securely with the addition of a folded up polishing cloth in front of the bell. My 1949 Buescher 400 also is safe and secure, but does not need the cloth as it has the larger bow. The backpack straps are an improvement on the earlier ones, the clips are really well made.
