Trumpet Mouthpiece Marcinkiewicz E12 Allen Vizzutti The size is 17.02mm, roughly the size of a Bach 3. The rim is not flat, but rather a rounded shape, and feels somewhat thin. The cup is a shallow bowl shape, similar to a Bach F. Like Monette and Eric models, the throat has a long straight section, which helps stabilize the sound. Allen Vizzutti himself is a classical and jazz musician, so this mouthpiece makes it easy to hit high notes while still producing a full sound, making it a versatile mouthpiece. This is the perfect mouthpiece for those who usually use a larger size and want to try a shallower one. I myself originally played classical music and then moved to a big band, and I purchased and used this mouthpiece during that transition period. I am selling it because I have purchased a narrower and shallower mouthpiece. Therefore, the frequency of use was not very high, and although there are some scratches from use, there are no dents. Please judge the detailed condition from the photos. Thank you for looking.
