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 UC-M1 model, this original model features abalone in the purfling inside the binding and in the rosette around the soundhole. It also boasts rare specifications such as a slightly thinner body and a longer scale length, combined with curly koa wood that has a distinct grain, which has become truly rare these days! 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 features a concert-style long neck and a thin body for easy handling. The tenor-equivalent scale produces a bright and resonant sound with solid bass and richness. 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): AB20378430 Total length (mm): 597 Body width (mm): 203 Hard case included
