I am a clarinetist with 57 years of professional experience, but not a repairman. However, I have never sent my instruments for repair. I do everything myself! I am asked by professional colleagues to repair their instruments. I learned the basics of repair from a 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 also worked 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. YCL450 Produces a mellow and powerful sound. CC Shiny Case Yamaha Mouthpiece Ligature Vandoren NICE!
