5C Eb alto saxophone mouthpiece from Standard series that is made out of high quality phenol resin (plastic) and features a design based upon the top grade Custom series. It provides a somewhat richer tone with greater variety of colours than 4C and excellent flexibility and response, which makes it very popular with soloists. The facing of the mouthpiece is slightly shorter than that of the Custom series making it easier to play, and easier for beginning students to achieve a rich characteristic sound. Tip opening: 1.7 mm.
