Re: Squeaky notes
For one thing, if it's 10 to 15 years old, you might want to get a new sax, BUT heres some suggestions....
For one, try looking at the palm keys, if they aren't coming down all the way, that can cause a lot of squeaking. This has happened to a lot of old saxophones I've dealed with.
You could also try checking if theres any holes in any of the pads, or pieces of the pad that are abnormally sticking out/in.
