A premium, filed reed that offers a rich, warm tone, a heavy spine that promotes dynamic flexibility, and exceptional tone quality in all registers, a long vamp profile to produce consistency of response, and a traditional tip thickness for ease of articulation. Reserve reeds are crafted using naturally-grown cane from D’Addario’s own foreign fields. D’Addario has pioneered the first practical and precise system to digitally measure and cut the incredibly complex geometrical patterns necessary to re-invent single reeds. Reserve reeds are cut to the tightest tolerances, offering the most consistent performance. 5 reeds per box.
