Like the instrument, Laskey Tuba Mouthpieces are a towering presence in low brass playing. With a thicker sound and more complex geometry, every aspect of a Laskey Tuba Mouthpiece, from the iconic rim to the exterior shape and cup, has been carefully designed to provide the clear articulation, precise slotting, and crisp response.

The B Series Tuba Mouthpiece is a deeper version of the G Series, providing a wonderful, full sound in the low register. A great choice for those trying to make smaller tubas sound bigger.

After testing numerous tuba makes and models, two shank sizes were developed to meet the needs of a wide variety of mouthpiece receivers: American (US) shanks fit most American made and styled instruments, while European (EU) shanks fit many European made and styled instruments, with the exception being most 6/4 CC tubas, which require the EU shank.
