How do I change cork on my saxophone neck?

Have it done! Don't take a chance on screwing it up. ie. taking finish off, scratching, denting, bending. Take it to a professional, they should be able to do this for you in a short amount of time and they are insured or can repair the damage if any. This is what I would do to my black nickel Tenor by Dave Guardala.

Take it to All County Music, they will fix it for you for a cheap price and fast.I wish I could give you the adress but i'm too lazy to get up and i'm doing registerd lip slurs while *insert..........yawn.......* typing.

Yeah, I concur with those saying to take it to the shop. You could also buy the kind that you can stick on there, but why risk it? It's not going to be that expensive.
