The Vandoren OPTIMUM series was the fruit of research on both external shape (particularly the beak) and sound, in order to meet the needs of today’s saxophone players. OPTIMUM mouthpieces are favourites of classical saxophonists.
The BL5 is the classical open mouthpiece inspired by the BL3. It features a large and round sound. It has a 235 (1/100 mm) tip opening and a large facing length.
