I learned the basics of repair from Buffet Crampon technicians when I was young. I am often asked to make adjustments by my fellow professional musicians. After retiring from the orchestra, I performed in New York and Berlin! I have released three CDs and held numerous solo concerts. I have participated in countless recordings and broadcasts. The fourth corner of my clarinet life! I hope to be of service to clarinet enthusiasts. Buffet Crampon R13 A representative masterpiece of the Buffet Crampon company. I feel the completion of the French system clarinet. Both the Festival and the Tosca have this R13 inner bore. Thinking of the many famous players who have held this R13 and left behind numerous historical performances, I can only say that I am overwhelmed with emotion. The usage frequency is extremely low, so it is in super beautiful condition. Exceptional sound, rare. I highly recommend it with confidence. Thank you for viewing.
