A thick blank reed that offers a rich, warm tone, a heavy spine that promotes dynamic flexibility and exceptional tone quality in all registers, a narrow rail slop to produce consistency of response, and a traditional tip thickness for ease of articulation. The D'Addario Reserve is a traditional blank clarinet reed that offers a focused sound, a shorter vamp for even response, rounded tip corners for tonal warmth, and a standard tip thickness for quick response.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.
