The Kinnaird Carbon Fibre Drone Reed Set was redesigned to produce a bright and resonant tenor sound without being buzzy. The very popular Kinnaird bass reed is largely the same as the original design Kinnaird Carbon Fibre bass drone reed with slightly more power. A metal set screw and allen key allows for easy adjustment of tuning height. The reed seats are Glass Fibre and stronger than other brands. Pitch can be adjusted with the tuning screw and O-ring bridle to control air flow. The reeds have a curved Carbon Fibre moulded, cane like tongue. The Kinnaird Evolution drone reeds offer outstanding air efficiency, are easy to set-up and offer excellent moisture resistance.
