The repair work is perfectly done. The bright, rich, and transparent sound of the C13 has been revived. The airtightness is perfect. Intonation, balance, and resistance are also perfect. It's wonderful. It exudes the aura of a masterpiece. I am a clarinetist with 57 years of professional experience, but I am not a repairman. 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. I have performed in New York and Berlin after retiring from the orchestra! 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 C13 Designed with the same specifications as the Buffet Crampon's representative masterpiece, the R13. I feel the completion of the French system clarinet. Both the Festival and Tosca models use this R13 bore. I am overwhelmed when I think of the many historical performances that numerous masters have left with this R13. It is in excellent condition because it has been used very little. Exceptional sound, rare. I highly recommend it with confidence. Thank you for viewing.
