The trumpet mouthpieces in the M series offer five rim sizes and two cup depths as well as three weight variants. The light version is primarily designed for orchestral trumpets, the medium version allows flexible use across different styles, and the heavy model fits perfectly with our Giolo and JooJazz models. The mouthpieces offer a good balance of sound, response and intonation and are perfectly matched to our instruments. With these options, the M series allows for both a subtle and precise orchestral sound as well as sufficient projection for big band applications – with the same mouthpiece size and without changing.
