I have been playing Gleichweit mouthpieces for many years. I always appreciated the precision of the production. But what I especially admire is the freedom they provide me while playing. A wide range of harmonics completely meets my sound criteria: the warm and flexible sound. It has always been a big pleasure for me to play Gleichweit mouthpieces!
