For more than 19 years, I play on Gleichweit’s mouthpieces with the highest satisfaction—both on the B-flat clarinet and the bass clarinet. It’s not just his technical expertise but also his personal qualities that I truly appreciate.

He is committed to quality, consultation, and the satisfaction of his customers. I have experienced this firsthand, but I also hear the same from my students and fellow musicians.

What I value most is his ability to cater to individual needs, whether it’s a specific sound concept or the anatomical characteristics of the musician. The quality of his mouthpieces is exceptionally high, yet with his keen sense of sound and expertise, he continually finds innovations to further improve them.

Simply phenomenal!
