A propos des lclarinette en ébonite ai trouvé en suivant ce lien:
https://clarinetcorner.wordpress.com/20 ... o-stomach/
cette info intéressante:, en anglais mais facilement compréhensible:
...the best ebonite clarinet available today is the Lyrique clarinet designed by William Ridenour. It is about a third as costly as the greenline, has a beautiful response and it dead-on as far as tuning in concerned.
This is an instrument which is manufactured in China and finished in Texas by the designer and tuning is exemplary. These also have not been known to crack. The dimensional stability is excellent.
Voila pourquoi on voit toujours sur les vidéo, William Ridenour dans un modeste atelier avec un outillage artisanal, difficilement compatible avec une production maintenant significative et des délais assez courts?.
