Vandoren V-12 Bb Clarinet reeds

V•12
V•12 reeds are manufactured from cane tubes with the same diameter as  cane used for alto saxophone reeds. As a result, they have a thicker  heel and are cut on a longer palette with a slightly thicker tip than  the Traditional. The longer palette means that more of the reed is  vibrating, resulting in a deeper, richer sound. The thicker tip gives  body to the attack and also increases the longevity of the reed.
The  introduction of the 3½+ strength allows a smaller and more specific  gradation, resulting in reeds that are more consistent within the same  strength.
The V•12 has expanded to include the Eb and Bass clarinet reeds, which offer a warm, rich and powerful sound.
