The Laskey 28G tuba mouthpiece provides the perfect foundation for success on the tuba! Scott Laskey designed the 28G as a small/medium mouthpiece capable of working well with many different sizes of instruments. Every aspect of the mouthpiece is designed to help the tubist overcome the typical issues of clarity of sound, articulation, and range.
The "G" refers to the Geib profile of the cup which uses a medium deep bowl. Tubists often prefer to match Geib cups such as the Laskey 28G with rotary tubas.
