The elegance of a masterpiece is overflowing. I am a clarinetist with 57 years of professional experience, but not a repairman. I learned the techniques of repair from Buffet Crampon technicians in my younger years. I am often asked to make adjustments by my fellow professional musicians. Performances in New York and Berlin after retiring from the orchestra! Released three CDs and held numerous solo concerts. Countless recordings and broadcasts I have participated in. The fourth corner of my clarinet life! I hope to be of service to enthusiasts. A representative masterpiece of Buffet Crampon. I feel the completion of the French system clarinet. The Festival and Tosca also have this R13 bore. Thinking of the many famous musicians who have held this R13 and left behind numerous historical performances, I can only say I am overwhelmed. It has been used very little, so it is in excellent condition. Exceptional resonance, rare. I highly recommend it with confidence. Thank you for viewing.
