The KTI-30 featuring a mango top with mango back and sides and Macassar fingerboard and bridge. Has a nato neck and nubone nut and saddle. It is a well-sounding ukulele and would suit beginner or intermediate players. With open guitar-style machineheads and an open pore natural gloss finish, the uke is beautiful. A characteristic feature of KAI instruments is the additional resonance hole and the slightly cut neck head, reminiscent of the ocean wave.
