The instrument is in perfect condition. I am a clarinetist with 57 years of professional experience, but not a repairman. However, I have never had my instruments repaired. I do everything myself! I am asked by professional colleagues to repair their instruments. I learned the basics of repair from a Buffet Crampon technician when I was young. After retiring from the orchestra, I performed around the world. Along with my performance activities, I was involved in the development of new YAMAHA products and also worked as an inspector for major musical instrument stores. The fourth corner of my clarinet life! I hope this will be helpful for those starting out. YCL452 Produces a mellow and powerful sound. Comes with the original case cover and the classic French mouthpiece, Vandoren 5RV. NICE! Perfect for school band use! A masterpiece that I can confidently recommend. Thank you for viewing.
