Working with Johannes Gleichweit is simply fantastic. Since switching from the Boehm system to the German system—specifically Viennese clarinets—more than 13 years ago, I play exclusively on Johannes Gleichweit's mouthpieces and facings. They are characterized by an incredibly homogeneous, round sound across all registers and dynamics. Particularly noteworthy are the easy response, effortless staccato, and perfect intonation. When searching for the perfect setup, Johannes takes as much time as necessary to ensure every customer is completely satisfied.
