Highland Reeds Drone Valves DV5

Drone Valves from Highland Reeds – set of three. These drone valves are easily adjustable with a simple screw, which means that they can be personalized to your preferred blowing strength. They work smiliar to a One-Way valve for drones, but offer resistance to limit the amount of air reaching the drones. It is extremely important to set your drone reeds to take less air since they will be receiving less.
When used properly, the Highland Reeds Drone Valves will assist with strike-ins and cut-offs, regulate air flow to the drones, and give a much steadier overall drone sound without "Peaks and Valleys".
A real help for pipe majors who need a uniform sound from their unsteady blowers
