However, I have never sent my own instruments for repair. I do everything myself! I am asked by professional colleagues to repair their instruments. I learned本格的に 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. YCL451 Produces a mellow and powerful sound. The excellent Vandoren 5RV mouthpiece is also included, which is wonderful. NICE! Perfect for club activities! A masterpiece that I can confidently recommend. Thank you for viewing.
