I heard a great mentor and colleague playing these mouthpieces and was impressed with the clarity of tone and „halo“ of sound audible from the back of the concert hall.

I’ve now switched to the 11-2 on Bb and model 19 on Bass clarinet, and both offer easy emission, stable intonation and flexible sound possibilities. 

A big benefit to these mouthpieces is their quality control across different copies of the same model, and I’m looking forward to consistency in my playing setup for years to come. Thanks to Johannes and Emir at Gleichweit for changing the mouthpiece game.
