This is the SHⅡ-CLE Lyric, modeled after Yasuhito Sugiyama, the tuba player of the Cleveland Orchestra. I've used it for a long time, but I'm selling it now because I haven't been using it recently. Therefore, there are some signs of use, scratches, and a barely visible dent in the shank, but it does not affect the performance. It has a large rim, but it feels light and is very easy to play, and Mr. Sugiyama himself said that it makes it easier to express the volume of p (piano). Quoted from the following site: Rim inner diameter: 32.92mm Throat diameter: 7.493mm Cup: Shallow U cup Released in 2023 by the Silky company, this is a new model supervised by Yasuhito Sugiyama, principal tuba player of the Cleveland Orchestra. It was developed based on the Silky Helberg II CLE model and designed for F tuba. It is a masterpiece that maximizes the appeal of the F tuba.
