I have a KTC-1 for sale here on UU . It is solid mahogany, and It is just slightly larger than the soprano with a bit more room on the fretboard. this uke has a wonderful tone and is a real joy to play. I had 2 vintage Martin 0's and this one had a very similar tone with a bit more volume. I sold the Martin's and I kept this one. It is pricier than the KS-1, but the Martin concerts are usually more. You don't usually see too many of these used, few sell them once they get them.
