The instrument is in perfect condition. I am a clarinetist with 57 years of professional experience, but not a repairman. However, I have never sent my own instruments for repair. I do everything myself! I am asked to repair instruments for my professional colleagues. I learned the basics of repair from a Buffet Crampon technician when I was young. After retiring from the orchestra, I performed worldwide. Along with my performance activities, I was involved in the development of new YAMAHA products and served as an inspection player for major musical instrument stores. The fourth corner of my clarinet life! I hope this will be helpful for those starting out. Includes the standard Vandoren 5RV mouthpiece! Produces a mellow and powerful sound. The case cover with a strap is convenient and stylish. NICE! Perfect for school club use! A superb instrument that I can confidently recommend. Thank you for viewing.
