It sounds as if these are good then. I raised it mainly because of the problems people have been experiencing transporting instruments with airlines tightening up on what can be taken into the cabin, or charging extra for shipping instruments (see other recent threads on this).

It sounds as if it could be worth considering, if for example you have an overseas tour for a few weeks. You could assemble it once there, and keep it like that until you fly home. You could carry a gig bag in your luggage to use while on tour.

Maybe we'll see more different versions if the idea is successful. I assume it could be applied to other stringed instruments, where these are big enough to justify it (not much point for a soprano uke!)
