Through a little knurled screw at the back side of the recorder head joint the width of the windway exit can be varied by raising or lowering the block in place.
Through this it is possible to adjust changes in the windway width in no time at all, for example by swelling of the block caused by long playing. An additional interesting aspect of the adjustable block is the opportunity to access well directed sound variety through variation of the standard windway width.
With the ’Adjustable Block‘ you can realize your individual ideas of sound in an easy way.
The wellknown problems of narrow windways, for example hoarseness are solved by the adjustable block (patent R. Strathmann).
We provide the mentioned models with the adjustable block on request.
Even retrofitting is possible.
