This is a one-of-a-kind custom model, ordered by Ikebe staff who selected the finest koa wood at the Yairi factory! Based on the latest UC-M3 specifications, this original model combines it with curly koa wood, which has become truly rare these days, and features a clearly defined wood grain! This exquisite koa wood was personally selected by Ikebe staff from the Yairi factory in Gifu Prefecture, chosen from their precious stock. Combined with the ivy pattern on the abalone rosette around the soundhole, it creates a magnificent finish that seems to fuse the sacred nature of Hawaii with the craftsmanship of the Japanese. The sound has a solid core yet a low center of gravity, producing a superb tone that simultaneously conveys beauty and stability, making you want to play it forever. This model is a concert size, with a thin body that makes it easy to hold, and a medium scale that produces a balanced tone that responds to any playing style. Needless to say, the wood is of exceptional quality, but the specifications themselves make it a special model, with only one existing in Japan. If you want to experience the true essence of Japanese-made ukuleles, please pick one up!TOP:Selected Highly Curly Solid Koa BACK/SIDE:Selected Highly Curly Solid Koa NECK: Mahogany FINGERBOARD: Rosewood BRIDGE: Rosewood Nut width (mm): 35 Scale length (mm): 378 Total length (mm): 597 Body width (mm): 203 Hard case included
