Cap SP About the Buffet Crampon C13: A model for professional musicians, designed with the same specifications as the R13, CONSERVATOIRE (Conservatory). R13 is a design term referring to the inner bore. The adoption of this miraculous inner bore has made groundbreaking improvements in intonation, sound quality, tone, and balance, earning it the immense trust and popularity of professional musicians worldwide. It has been the representative of French system clarinets since its release in 1955 and is still in continuous production. About the maintenance: 1. Body tone hole cleaning and oiling. 2. Complete pad replacement. 3. Key distortion correction and polishing. 4. Spring cork inspection and partial replacement. 5. Ring height adjustment. 6. Pad gap adjustment. 7. F1 (upper and lower joint connection) adjustment. 8. Lower joint CB connection adjustment. 9. Overall balance adjustment and fine-tuning. 10. Play-testing across the entire range. The repair is perfectly finished. 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 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 use the R13's inner 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 is in super beautiful condition because it has been used very little. Exceptional sound, rare. I highly recommend it with confidence. Thank you for viewing.
