McCallum Drone Valves (Bagpipes) :
These valves help to control airflow to the drones and aid the player with striking in and cutting off the drones. They are made of plastic with a rubber non-return valve. It sits firmly in the blowpipe-stock with aid of a rubber o-ring. Airflow can easily be adjusted by moving the rubber ring.
