This is a thick G-key kena made from madake bamboo. It is tuned to approximately A=442Hz. ・Size: Total length 35.8cm, mouthpiece inner diameter approx. 23mm, wall thickness approx. 4.2mm, largest finger hole diameter 11.5mm, mouthpiece width 10.5mm, mouthpiece depth 7mm ・Surface finish: Self-oiling during oil extraction + partial application of camellia oil ・Weight: 114g This is made from a very hard type of madake bamboo (a material that makes the maker cry). The mouthpiece carving turned out as I envisioned, and I feel refreshed. Please experience the powerful tone produced by the dense structure. Instant purchase is welcome.
