Fibracell Saxophone Reeds are made of an advanced composite of very stiff but sound absorbing Aramid fibers suspended in a light weight resin matrix. Fibracell Reeds have the same woody tone as cane but with improved sound projection and are excellent for doublers because they do not require soaking. Playable in all weather conditions, Fibracell Reeds are unaffected by heat or humidity. Fibracell Reeds do not swell, warp, or soften when wet and last up to six times as long as cane reeds. Quick response for better articulation, excellent pitch control and intonation in all ranges, and brilliant overtones for a full, vibrant, resonant tone are what musicians count on from Fibracell Saxophone Reeds. Fibracell's excellent durability is due to a bonded film on the bottom that helps resist tip splitting
