Bach trumpet mouthpiece 11EW. Purchased new and only used occasionally as a spare, so it is in generally clean condition. Comes with a box. It has an inner diameter around Bach 10-1/2 with a wide cushion rim, and the outer diameter has enough tolerance that players of mouthpieces like the 1C can transition without discomfort. The cup depth feels to be between a Bach D and E. The rim has a very comfortable feel, provides good endurance, makes hitting high notes very easy, and produces a rich tone. Thanks to the rim, which is similar to a Rudy Mack, low notes are surprisingly easy to play, and thick subtone is also easy to produce. It has a very similar character to the New York Bach 17C1, which Clifford Brown is said to have favored, with a slightly larger diameter than the 17C1. Like Clifford Brown, you can easily play from subtone to piercing high notes. While it can certainly be used as a main mouthpiece, it would also be good for players who usually use larger mouthpieces to switch to for high notes, when endurance is needed, or for piccolo trumpet. It felt very agile and allowed for focused playing. It is in relatively good condition, but as it is a used item, please check the photos for its condition before purchasing.
