The newly developed Tuba mouthpieces were created with the same principles of all K&G designs. These mouthpieces come in a range of seven different rim sizes, ranging in size between 30.5mm and 33.5mm. The well-balanced cup produces a robust and broad sound in all registers. The cup’s design helps the air flow smoothly to the throat, transforming all the air in full resonant dark timbre with a clear articulation, followed by measured resistance. All these features result in the player having maximum control and pitch stability.
