For Tenor Trombone A mouthpiece bearing the name of the world-renowned trombonist "Christian Lindberg." Its distinctive rounded form is impressive. Cup Diameter: 25.00mm Equivalent to a Bach 6-3/4C size. New price: around 20,000 to 30,000 yen ★Personal Impression Similar to the Lindberg model for large bore trombones, the throat is large, allowing for a solid air stream. It responds very well and offers high flexibility. However, relying on the instrument's characteristics can lead to fatigue, so maintaining a solid aperture yields good results. Transitioning from a large bore mouthpiece is smooth. Also, signature models from other companies like Michael Dease, Marshall Gilkes, and Wycliffe Gordon often have sizes of 6 1/2 or larger, suggesting a concept of increasing freedom while maintaining a degree of physical control.
