I'm selling this mouthpiece, which I used for about six months on my C tuba after purchasing it, but I couldn't get used to it. Originally priced at 58,300 yen (gold-plated finish), it comes with the original box. There are minor, inconspicuous scratches from use on the outer rim and shank, but there are no dents or other damage to the shank. I'm sorry, but I cannot accept price negotiations. Thank you for your understanding. [From the retailer's catalog] ・KS-CⅢ (Rim diameter: 33.00mm, Throat diameter: 8.42mm) A tuba version of Walküre, supervised by Koji Suzuki of the Kyushu Symphony Orchestra. It features an overwhelming resonance and consistent resistance. For CC tubas. The beautiful sound produced by the thinnest rim color in the series is a characteristic. Ideal for chamber music. Shank is Regular.
