A vintage mouthpiece perfectly suited for Bach 36B and Yamaha's so-called medium-small bore trombones, as well as small shank euphoniums and baritones like the YEP-321(S) and YEP-201. This VINCENT BACH mouthpiece is loved by a wide range of players worldwide, from beginners to professionals. It is said to "improve poor instruments and make good instruments even better. It provides rich volume, excellent intonation, good response from high to low notes, rich resonance, even tone across the entire range, and moderate resistance to prevent player fatigue."

Vernon era." The specifications are "4" and the catalog states: "Cup Depth: M, Cup Inner Diameter: 26.00mm, Rim: MW, quite a round rim. A model with a fairly large cup. Popular with players who have a strong and stable embouchure." For small bore instruments. Total length 7.9cm, 150g. Current new retail price is 15,730 yen. Used. Although not captured well in the photos, a faint "A" like character is stamped on it. Also, the shank tip is slightly deformed. Please refrain from purchasing if you are concerned.
