The Natural models are the original Fiberreeds made of only the white hollow-fiber material designed to imitate the structure of Around Donax cane. This plain white material produces a pure tone that allows one to create a different sound with the varying techniques one might use to change the tonal qualities, including the biggest range in overtone and altissimo playing. In the mid and low range they produce a satisfying full-bodied sound.

The Natural Classic Fiberreed has the steeper classic cut, making it sound darker and smoother than the regular Natural. It lends itself especially well to the vintage jazz sound or to a classical music sound on mouthpieces like the Selmer C*.
