A Deep and Rich Clarinet Tone
The Vandoren V12 Bb Clarinet reeds are manufactured from cane tubes with the same diameter as cane used for alto saxophone reeds. This results in a thicker heel. Additionally, they are cut on a longer palette with a slightly thicker tip than the Vandoren Traditional Reeds.
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 increases the longevity of the reed.
The introduction of the 3 1?2+ strength allows a smaller and more specific gradation, resulting in reeds that are more consistent within the same strength.
