Drone Valves from Highland Reeds – set of three.  These drone valves are screw adjustable which means that they can be accurately set to suit your blowing strength and don’t fluctuate with bad blowing.  Benefits are:

  • Assisting with strike in and cut off
  • Accurately set to suit your blowing strength
  • Regulate air flow to the drones giving a much steadier drone sound
  • A real help for pipe majors who need a uniform sound from their unsteady blowers
