Adjusting Ezeedrone Reeds
The first set of plastic drone reeds which I bought
In recent years, I have used only Ezeedrone reeds so I cannot talk about other maker's reeds.
There are two adjustments which affect the striking-in characteristics and pitch of the drone.
Moving the rubber bridle - a fraction - makes a huge difference to the volume of air which the reed takes and the way it strikes in.
Making the tongue shorter increases the pitch of the drone - see below.
Moving the tuning screw also changes the pitch - see below.
Eventually, the bridle becomes "tired" but the good news is that it can be replaced by the manufacturer - Pipe Dream Reeds in Glasgow - for a modest fee as part of a refurbishing service.
