Gary Flowers on the Umbra Clarinet F1

"I bought a Chedeville Umbra F1 clarinet mouthpiece from you at the clarinet festival in Reno this summer.
I just wanted to let you know that has been a great mouthpiece. The sound is rich and full. It gives great flexibility, great response . It has stabilized my altissimo register. In short it is a great mouthpiece. Thanks also for your time in helping me select it. My reeds are lasting longer too."
