YAMAHA Bb Professional Clarinet Model YCL651 Made of Grenadilla No cracks or repairs Serial number 010××× Superb condition Accessories YAMAHA genuine hard case YAMAHA genuine mouthpiece 4C Genuine ligature Cap YCL651 The professional model clarinet that the world's YAMAHA first challenged. A culmination of large capital investment and Japanese technology. The YCL62, the predecessor to this YCL650, was the clarinet used mainly by Buddy DeFranco, the best jazz clarinetist of this century. The YCL651 is its successor (¥291,500 at the time of release) Due to the narrow inner diameter and YAMAHA's technology: 1. Overwhelming responsiveness. 2. Stable quality due to accurate design and manufacturing. 3. Accurate intonation and flexible balance. 4. Resistance to withstand strong playing and a bright, rich tone. 5. Durable design that can withstand heavy use. I understand why Mr. DeFranco chose it. About maintenance. 1. Tone hole greening and oiling of the body. 2. Complete pad replacement. 3. Spring cork inspection and partial replacement. 4. Key distortion correction and polishing. 5. Pad gap adjustment. 6. Ring height adjustment. 7. F1 (upper and lower joint connection) adjustment. 8. Lower joint CB connection adjustment. 9. Overall balance adjustment, fine-tuning. 10. Replacement of the thumb rest with a movable type. 11. Test playing and confirmation of all ranges. The adjustment is perfectly finished. The overwhelming responsiveness is still there. I feel joy overflowing in the bright and vibrant tone. Extremely resonant! I am a clarinetist with 57 years of professional experience, but I am 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 have performed in Berlin and New York. I have held numerous solo concerts and have released three CDs, and I have participated in countless recordings and broadcasts. The fourth corner of my clarinet life! I hope to be of service to clarinet enthusiasts. Anyway, it sounds great. High notes with extension, transparent mid-range, and flexible low-range! Energetic and vibrant, it's the best! Includes the included mouthpiece YAMAHA genuine 4C! Ideal for club activities. I highly recommend it with confidence. Thank you for viewing.
