Available in one facing CX_EB, this mouthpiece posesses a strong clear sound quality.CXZ_EB - One Facing - Professional. Will use standard Eb clarinet reeds. Personally, I recommend Vandoren V12 Bb soprano clarinet reeds, cut short at the end (use scissors!) This mouthpiece provides a clear and incisive tone, excellent intonation, and the ability to hit and control the highest notes on the horn. Play the F#, G, and G# with improved intonation, and stability that you have never enjoyed before.
