Thank you for viewing. Kern Nat Trumpet Key B♭ ML bore 11.65mm Bell diameter 123cm Beginner to experienced player Pistons move smoothly without sticking. 1st and 3rd triggers allow for smooth pitch correction during performance. Good airtightness and a light, responsive sound! After initial treatment, the lacquer was removed with solvent, and a stitch process was applied, followed by a brushed satin finish. It has a dry sound and a cool, jazzy appearance! No pitch deviation. Suitable for jazz numbers, popular music, bebop, bossa nova, fusion, rock, and big band. Mouthpiece: Non-manufacturer 7C, a standard type. Soft case, but unused. Soaked in baking soda and citric acid solution for 2 days, and the inside of the tubes were cleaned with a wire brush and neutral detergent to remove mold and dirt, making it very hygienic and ready to play upon arrival. Please consider this opportunity to experience a jazzy playing feel.
