Need a little more chop room? Brass players with larger lips often need a larger inside rim diameter. The Superflugel rim is medium round on the inside and rounded on the outside, with a generous inside diameter (.682″). This rim delivers maximum comfort even for extended play. The deep V cup, Legends FL flugel backbore, and heavyweight blank work together to give that perfect fluffy dark flugel sound. If you want to play flugel like a superhero, this is the mouthpiece for you!
