Beautiful solid Hawaii Koa wood. All the features of our Koa tenors (ebony bridge, fingerboard & binding; slim, comfortable neck with truss rod; super-smooth 18:1 geared tuners) but bigger; tuned like the 4 high strings on a guitar (EBGD). Alternately, with our special “baritone standard” strings, can be tuned AECG like all the other ukulele sizes. What you see is what you get!!
