The D'Addario Venn Bb clarinet reed is one of the most complex synthetic reeds on the market. By understanding the organic structure of cane, D'Addario have perfectly replicated the tone of an organic reed with all the benefits of a synthetic reed. D'Addario started by reverse engineering organic cane. They perfectly matched the structural nature of cane with polymer fibres and layered them with resin and natural cane particles. The result is this - a reed with the sound and performance of cane, but the consistency and reliability of a synthetic design.
