Yamaha trombone/euphonium mouthpiece. The shank is for large bore instruments. This is an old model, but it's new. There is no outer box, so the mouthpiece itself will be provided only. It was stored without the outer box, so there may be small scratches or dullness, but they do not affect the performance. (Please check the condition in the photos.) The size is [48], which is a good size for beginners. This mouthpiece has a very well-balanced rim and cup with a narrow backbore. It has the ability to meet the advanced demands of professional musicians and is a highly complete mouthpiece. *Price negotiations are welcome. *Multiple purchases of this product are possible.
