Based on the design of the original hydroformed 62-style neck. the Custom C1 neck has the smallest bore taper of all Yamaha Custom saxophone necks. This particular bore design provides the player with the greatest possible control for a quick response, excellent intonation and a focused tone. Capable of a dark and husky tone, this hand-hammered French brass alto neck is a beautifully made, intensely expressive improvement for many horns.
