Vandoren SR6135 V12 Alto Saxophone Reeds - Box of 10Produced from cane selected for its specific proportions, V12 reeds have a thicker heel and are cut on a longer pallet with a slightly thicker tip than the Traditional. The longer pallet 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.
