RG Hardie 3D Printed Drone Extenders

Using state-of-the-art 3D printing technology, R.G. Hardie & Co. drone extenders change the effective length of standard pitch drone reeds to play in the key of B flat (466hz).
The set includes a bass and two tenor drone extenders. The drone reed fits into the extender, which in turn, is inserted into the drone reed seat.
