Model #993132
It has the characteristic of increasing the harmonic range, crucial in all instruments, thanks to the concomitance of the bells built into the valves.
This device greatly facilitates the dynamics of the trumpet itself giving a greater volume to the harmonics, from note to note. The bells are screwed to the valve.
With the clapper valve we accomplish something essential for the players: dynamic COMFORT that widely eases the performance.
This system is patented by STOMVI.
