All mouthpieces and instruments that figure in this website are built or rebuilt and played succesfully. It is possible to put this knowledge and skill in the service of other musicians.
The construction of mouthpieces and the refinements of instruments were not primarily done for commercial reasons, the motive rather was curiosity and perfectionism. But whoever has a serious interest can pluck the fruits from this garden, albeit not for free.
