Strength

Independent shopping perspective
Built for alto saxophone in the listed 2.5 strength, the ALTA AMBIPOLY Jazz Reed uses a symphonic material that takes on moisture and conforms to the mouthpiece during its initial pairing process. That pairing is intended to improve the seal, while the reed is described as delivering a warm, even sound across the registers. It can also be worked with a reed knife or sandpaper, giving players room to make their own adjustments. The material is designed for consistent strength and continued use without micro-cracks or fraying.
