Fully maintained Buffet Crampon E11, excellent sound, superb condition. Made of grenadilla wood. No cracks or repairs. Serial number 684XX Accessories: Original hard case Original case cover, leather type Original mouthpiece Ligature: Vandoren Rest: Adjustable, strap compatible Buffet Crampon E11 An intermediate model in Buffet Crampon's college model line. The successor to the Evette Schaeffer, which inherited the inner bore of the famous BC20, the mainstay of Crampon until the R13 was released. The narrow bore provides a quick response and makes it easy to play. Later, the college models became the C, E, and B models, which are the current lineup. About maintenance: 1. Body tone hole cleaning and oiling. 2. Complete pad inspection (using Pisoni leather pads). 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, fine-tuning. 10. Full range play test confirmation. Although in superb condition, there were some mechanical issues due to aging. The adjustments have been perfectly completed. Despite being a college model, it's a Buffet Crampon, the master of clarinets. A clear and refined sound has been restored. I am a clarinetist with 57 years of professional experience, but not a repairman. I learned本格的に from a Crampon technician when I was young. I am also 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 and participated in numerous solo concerts, recordings, and broadcasts, too many to count. The fourth corner of my clarinet life! I hope to be of service to clarinet enthusiasts. Buffet Crampon E11 An intermediate college model. Inheriting the history and tradition of Crampon, the authentic French sound has been revived. The near-new condition is extremely rare. I highly recommend it with confidence. Thank you for viewing.
