Willie's Trumpet Mouthpiece Excellent condition. Suitable for a wide range of uses, such as orchestras and wind bands. Personally, I feel it's a mouthpiece that combines the sound quality of Bach with the ease of use of Yamaha. It makes articulation clearer, so it's well-suited for French pieces and fast, staccato music. In terms of bore size, I think it would also work with rotary trumpets. The retail price was a little over 30,000 yen.
