The Laskey Classic F Series American Shank tuba mouthpiece provides mid-shallow bowl cup and crisp articulation suited for contrabass tubas. You'll achieve a full, resonant tone from your 6/4 CC or F tuba that cuts through the ensemble. The Laskey mouthpiece's broad rim and open throat facilitate easy blowing and clear projection. While similar to the Helleberg design, the Classic F Series mouthpiece boasts a shallower cup for enhanced control and focus. The silver-plated finish gives a bright, vibrant sound with excellent durability. For tubists seeking a mouthpiece that enhances their instrument's natural power and clarity, the Laskey Classic F Series delivers.
