Why does Fibracell sound so good Because it's not plastic and it's not cane. It's the most highly developed composite structure ever engineered for woodwinds! Fibracell material is a sophisticated composite of aerospace materials designed to exactly duplicate the way nature constructs cane reed. Very stiff but sound absorbing Kevlar fibers are suspended in a lightweight resin formulation. With a Fibracell you get: The same "woody" tone as cane but with better sound projection. A reed that is great for doublers because it does not require soaking. A reed that is playable in all weather conditions, not affected by heat or humidity. A reed that does not swell, warp or soften when wet. A reed that lasts up to six times longer than cane with no unplayable reeds, making it less expensive to use than cane. Quick response for better articulation, excellent pitch stability and intonation in all ranges, even for the clarinet. Brilliant overtones for a full, vibrant, resonant tone.
