I purchased this cornet mouthpiece because I wanted to try one with the same cup as the Schilke 14A4a, which is a famous mouthpiece for reeds. (The photo on the left is 14A4X, and the photo on the right is 14A4a) -------------------- ＜Catalog Specifications＞ ・Cup Inner Diameter: 17.09mm ・Throat: 27 ・Features: Based on the popular 14A4a, the adoption of a large "X" backbore provides a very open playing feel. Enhances the playing feel and tone of a Silky piccolo trumpet. Also suitable for E♭ cornet. -------------------- The item for sale has only been test-played a few times and is in almost new condition. The original box is also included, so I will sell them as a set. The item will be wrapped in bubble wrap and shipped via Yu-Packet Post Mini.
