VENN Generation 2 by D'Addario Alto Sax Reed  Strength 3.0 

D'Addario VENN Generation 2: an advanced synthetic reed constructed of polymer fibers, resin, and natural cane elements. 

Designed to give players the benefits of synthetic reeds without compromising on the sound and playability of cane reeds.

Developed by the industry’s most revered engineers, VENN signals a whole new era in woodwinds innovation: combining the stability and longevity of a synthetic reed with the sound and feel of natural cane. To mimic the organic structure of cane, we reverse-engineered cane itself, layering different strengths of polymer fibers with resin and natural reed elements to make up the reed blank
