I am so glad to hear you are stumped too! I have been searching the internet ’cause I want one too! Initially thought it was the Yamaha P25F but clearly isn’t when closely inspect the picture (color not as vivid and the case is much different). I have seen him play it on the Colbert show as well. Really cool. So I broke down and ordered the Yamaha ’cause I just really want a small one to travel with and don’t like to take my vintage Hohner Piana 27 or 26 on the road. I really love the little guys! As to the uke, my ukulele is a simple little dolphin Makala but has great Aquilla strings that come on it so it sounds pretty good!
