Thanks for doing the mm Pete. I currently play a concert which is 34-35. I really like the sound of the vita and thinking of buying one but there are none close to me to try. Have you played a concert? do you find it a squeeze length wise.Just measured mine at 1 5/16 or 34mm
Ohana call the CKP a concert size although I think this owes more to the size of the body than anything, which is quite large, as the scale length is soprano.
Must admit, I prefer tenor ukes for comfort as my sausages are quite pudgey, so concert is not an issue for me, though I do find sopranos a bit of a squeeze. That says more about my playing style than anything though.
Where in the World are you Phil? I'm getting a UK vibe?
