Greg Black 25th Anniversary Mouthpiece For Hozoma Tenor and Alto Small shank (for narrow bore). In recent years, they have hardly been manufactured, and since those who own them don't let them go, it's difficult to obtain them on the market. The size is 24.70mm. The rim is flat and medium wide. The cup is medium-shallow. This mouthpiece has a thick, core sound and good response. The sound doesn't diffuse around the receiver, and it feels like it resonates from a distance from the bell. There are no major scratches or dents that would interfere with playing. Please check the images.
