This is a pristine condition Yamaha Custom G1 series neck for the alto sax. This is an unlacquered, bare brass neck, the best option if you are looking for the freest, most resonant neck around. The UL neck shows some light discoloration/tarnishing but little wear of note; just a couple stray surface scratches if you look very close. No dents, dings, or previous repairs. Will fit modern modern and vintage Yamaha horns. Tenon measures .962”, if you want to see if it will fit something else.
