Kinnaird Evolution Drone Reeds – The Kinnaird Carbon Fibre Drone reed was redesigned in 2013 to improve the brightness and brilliance of the tenor reeds. The Kinnaird Evolution Drone Reeds are bright but not buzzy. The very popular Kinnaird Bass reed is largely the same as the previous design with slightly more power. Similar to the Kinnaird Carbon Fibre Reed, a metal set screw and allen key allows for easy adjustment of tuning height. The reed body and seats are glass fibre and stronger than other reeds. Pitch adjustment is with the tuning screw in the nose cone. The o-ring bridle is used to control air flow. These reeds are extremely air efficient. They are easy to set-up and offer excellent moisture resistance. The reeds have a curved carbon fibre molded tongue. If you play an easy reed or struggle with your pipes, consider the “Easy” version which come set up out of the box easier than our regular reeds.
