I really enjoy Ohta-sans vids on Youtube, and I wonder about the older uke that he usually plays. It looks a bit small for a concert, but has the extended frets on the fingerboard. Is that instrument a soprano, super-soprano, or a concert?
I know that he does now, but not in the past. The ones on Youe tue are very dark with a white binding. I believe that Kamaka used to build for him, but not sure. The body on these looks too small for a concert.
This one? http://www.flickr.com/photos/tdlcfoto/4807870221
I thought it was a vintage Martin, but I'm not certain.
