BACH Mouthpiece For Trombone and Euphonium 4G For Large Shank This is a used item, so there are some scratches and minor dents, but it is in very clean condition overall. The plating is completely intact. In recent years, the trend has been towards larger instruments and mouthpieces, heavier and more powerful. This is a mouthpiece you'll definitely want to get your hands on! It does not come with the original box, so it will be wrapped in bubble wrap for shipping.
