C2 S3 This new mouthpiece has already become quite popular just by word of mouth since Wynton started using it earlier this year. Dave Monette took over a year to develop this design, making too many prototypes to remember! The goal was simply to design a replacement for the C2 that was better in every way. Dave wanted a mouthpiece that had a richer, livelier sound, a faster response, and larger "targets" on each note… oh, and an easier upper register too! We did it.
