variable performance system

Have you ever wondered why the upper register on one trumpet is easier than another trumpet?

We know why this happens. In fact, we developed the Variable Performance System (VPS) to address this very problem. We guarantee you will find the correct VPS setting to fit your playing preferences in a matter of minutes.

We have invested over 26 years into research in physics, acoustics and modern manufacturing to bring you the most versatile and efficient brass instruments available on planet Earth.
