Yanagisawa Flute Head Joint This was purchased used, and the details of the manufacturing date are unknown. In my subjective opinion, it has a richer volume and resonance compared to silver. Compared to gold, I feel it has a complex resonance with a certain roughness, rather than smoothness. The tube body cracked twice, and I requested repairs from the manufacturer, but both times the cracks reappeared on the same day. After that, there has been no sign of the cracks expanding, and I don't feel any impact on the sound. The price is set considering the cracks. Please purchase with the understanding of this point. While I do not guarantee that there will be no problems in the future, it is currently usable without any issues.
