K&G Bastuba 4F Kurun & Gilbert

The newly developed Tuba mouthpieces were created with the same principles of all K&G designs. These mouthpieces come in a range of four 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.

The rim profile is the same as that used in all K&G designs and is engineered for extreme comfort, lip support, flexibility and high definition attacks.
