Rico Grand Concert Select Evolution Bb Clarinet Reeds, Strength 4.5, 10-pack

Grand Concert Select Evolution reeds are unfiled and have more material in the shoulders of the vamp. They feature a traditional tip and the thickest spine of the GCS family, providing a full sound. Of all Rico's clarinet reeds, GCS Evolution has the thickest blank; thick blanks are made from cane further away from the bark, resulting in a warmer sound.
