"The Chedeville UMBRA Clarinet F1 is the best mouthpiece I have ever played. I must say that I own over a dozen mouthpieces from several mayor manufacturers and the Umbra surpassed them all in every category. The sound is beautifully dark with many undertones that makes it colorful. The response is immediate and precise, allowing for a pianissimo to a triple forte to be played effortlessly in any register and single tonguing at speeds I wasn’t able before. More importantly, the intonation is impeccable."
