The Laskey Classic Series Large Shank Bass Trombone Mouthpiece provides a comfortable playing experience for serious bass trombonists. Its deep cup and large inner diameter produce a warm, resonant tone with precise articulation in all registers. The 90D and 93D models offer a balanced response for most players, while the 95D provides extra power for strictly orchestral performance. Designed with a traditional 1-1/4G size, the 85MD is a versatile mouthpiece to allow tenor trombonists to easily double on bass trombone. The silver-plated finish and large shank ensure a secure fit with most bass trombones. Whether performing solos, in a jazz ensemble or with an orchestra, the Laskey Classic mouthpiece helps you achieve the depth, clarity and control needed for any musical situation.
