Laskey Mouthpiece Tuba "F" Series

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 F Series Tuba Mouthpiece is similar to the Helleberg model, but approximately 1/3 shallower. Wonderful mouthpiece for 6/4 CC or contrabass tuba, and can also make the F or bass tuba 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.  American (US) Tuba Shank Measurements:Top: 15.44mm/0.608"Bottom: 13.31mm/0.524"Taper Angle: 1.41 degrees European
