However, I have never had my instruments repaired by others. I do everything myself! I am asked to repair instruments by my professional colleagues. I learned本格的に (honkakuteki ni - in earnest) 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. YCL452 Produces a mellow and powerful sound. Comes with a genuine case cover. NICE! Perfect for club activities! A masterpiece that I can confidently recommend. Thank you for viewing.
