Tenor saxophone Selmer Series III GP neck. I am selling this because I no longer use it after changing instruments. The price is set at about half the price of a new one. Compared to a lacquer neck, the airflow is improved, and the sound becomes more brilliant. You'll feel like you've changed instruments. If you need it, I will include a Wood Stone neck case, so please let me know. The neck has discolored, but I haven't used it much since replacing it.
