Adjustable Drone Valves für Great Highland Bagpipes
Price for 3 pieces
K-Valves are a new type of drone valve for the Great Highland Bagpipe that offers a minimally restrictive air flow to the drone reeds and a crisp,
clean strike in and cut-off of the drone sound.
Some competition bands require their pipers to use a type of drone valve or plug for cleaner and more consistent attacks and cut-offs. Other pipers
like this feature for playing solo as they feel it gives them better control of their strike in and cut off.
One issue with other fine devices on the market is the reduced air flow into the drone reeds. While this restriction reduces the tone and volume from
the drones, it does aid the piper to blow steadier.
K-Valves are different in that they offer such a low air flow restriction that the degradation in tone and volume is hardly noticeable. We checked the
drones with a sound level meter and chanter stock plugged. The meter read between 85 and 87 db (decibels A scale) without the valves installed and
the meter hand held above the chanter stock. After installing the valves, readings were taken at the same point and were between 84 and 86 db. There
appears to be very little, if any, restriction.
K-Valves are fully and easily adjustable. Just hemp the body with whatever type of hemp you prefer and install in the bottom of the drone stocks. The
valve pre-load can be changed by backing the screw out to increase the tension on the rubber valve. Should more tension be desired, pull the elastic
thread further out of the rubber stopper in the head of the screw and slide the small rubber plug towards the valve in small increments.
It is not necessary to remove the K-Valves from the bag to balance the strike in point of your drones. With most pipe bags you can pinch the adjusting
screw through the bag and do not have to open it at all! This has not been a problem even for pipers with hybrid pipe bags. In many cases setup should
only take a few minutes.
