[From the seller's catalog] Signature model of Kazuhiko Sato, principal tuba player of the New Japan Philharmonic Orchestra. Rim outer diameter: 47.7mm / Rim inner diameter: 32.89mm / Throat: 8.2mm. It is designed with a slightly flat rim, a deep Helberg-type cup, and a thick European shank. Basically, it was created with the concept of maximizing the sound of the instrument when playing in ensembles such as orchestras and wind bands, but it also has good operability, enabling clear articulation and smooth slurs, making it a well-balanced mouthpiece.
