Valve casing and pistons
Thinner valvecasing and pistons, as well as the modified angle of the branch tube (knuckle), result in improved response and provide the performer with an ideal blowing resistance.
Button on the 1st slide
The button on the 1st slide is to fine-tune the blowing resistance for better control.
The height of the main slide water key gutter has been increased for optimum resistance, and the ends of the water key spring have been curled for improved response.
