About the founder:

I'm Maximilian Petz, born in 1998 and raised in Ehrwald, Tyrol. During my time at Musikgymnasium Innsbruck, an upper secondary focussing on education in music, I wanted a new golden suface on my mouthpiece, because the old one dropped of and the raw brass was showing. I spoke to a trombone colleague from my hometown wind band about that issue, who is also a coating-physician. After some discussion about the wanted properties of a good surface we decided to give "Artificial Diamond" a try. Practice sessions showed that this is an incredible innovation. Some months later I got to speak with Dany Bonvin (Munich Phil.) about the black mouthpiece and let him feel the coating. He was instantly excited about my product and wanted to try a "black mouthpiece" too. I thought, when Usain Bolt wants a running-shoe from you, you shouldn‘t hesitate to produce one of him and the same goes for Dany Bonvin. I founded the company Diamond Brass, in order to serve all those people, who want the opportunity to play on an innovative diamond-coated surface.

My actual job is making music as a basstrombonist, organist and music writer for my ensemble "Austrian Brass Consort". Currently I am studying at the Munich University of Music and Theater with Prof. Quirin Willert and Prof. Benjamin Appel. (both Munich phil.)

But what I really enjoy is getting to know other musicians like you and seeing how Diamond Brass excellerates progress, motivation and joy in playing.

I'm very open to your suggestions, or be it just a typical brass discussion about instrument, mouthpiece and literature.
I'm looking forward to your message!
