A veritable auteur of trumpet design, David Monette continues to pursue his vision of creating a trumpet with unparalleled sonic quality through the constant pitch center.

What’s more, you can bring premiere Monette control and tone to your existing instrument with a Monette mouthpiece. From introductory Monette First and First Leads, to their classic line, and contemporary Unity line, Monette mouthpieces are the first step on your path to achieving the tonal synergy of the constant pitch center. For brass players fervently chasing the perfect sound — choose a Monette.
