Eman is right on with listening. Your equipment is important, but knowing what to sound like is more important than anything. Joe Henderson played an old C* with the bulb on the end almost his whole life, and he is one of the most influencial jazz saxophonist ever. Don't try to take in too much at once. Pick a player you really like and solely listen to him for a week or two. This gets you familiar with that artists sound and in turn will allow you to imitate it better. Eventually you will want to buy a new piece. I am sure you have heard of all of these but here they are anyway, otto link, meyer(hard rubber not there metal), brilhart(ebolin), peter ponzol, dukoff.......... Try out as many pieces as you can, and take someone who knows the music with you (teacher...) so you can get their oppinion. Good Luck, and Have Fun!
