Thank you for viewing. This is a Tilz Baco model trombone/euphonium 5GS small shank mouthpiece. I received it from an acquaintance, but I'm selling it because I don't have a chance to use it. There is a distortion on the shank (see photo 4). There is a small black scratch on the inside (see photo 6). It will be shipped with a Snoopy mouthpiece case. There are some color scuffs, but it can be used without any problems. Please refrain from purchasing if you are nervous about used items. It will be disinfected and packaged. I will consider a small price reduction.
