stomvi complementos trompeta clapper piston Model #993132

The valve Clapper is a small brass bell screwed to the bottom of the valve.

This device greatly facilitates the dynamics of the trumpet itself, giving a greater volume to the harmonics, from note to note.

With the valve clapper we accomplish something essential for the players: dynamic COMFORT that widely eases the performance.

This system is patented by STOMVI.
