This is an item I purchased here before. It was very good, but I am selling it because I am purchasing another mouthpiece. I have only test-played it since I bought it. ↓ The following is quoted ↓ This is a masterpiece by Yoshiyuki Yamanaka, with a refacing and oxidized film Pluto finish. The bite plate is also undamaged, and the color is different only in the refaced part after the oxidation film treatment, but it is in the category of super beautiful condition. The protrusion on the back, seen on the STM, has been removed and refaced very carefully. The side and tip rails are finished very carefully and accurately. It produces a very cool sound with a hard reed. It's like a master link. The opening is 6★, but that opening is maintained. This is a mouthpiece from the Super double quotation era. It has a husky and jazzy tone. It is a professional-spec mouthpiece, but it is surprisingly easy to play, and it produces a sound from a Webster-like sound with a double lip to a normal jazz sound with a single lip, and it is simply a wonderful jazz sound. Please take this opportunity to purchase it. Mouthpiece only. Ligature is not included.
