A better sound in which way? I don't see anything wrong with your current setup. Try other mouthpieces by all means but IMO it's a self defeating thing for us novices.ab1990 said:
Even the "perfect" mouthpiece, is going to take weeks if not months, to adjust to and evaluate fairly. You've got to "get to know" the mouthpiece. What usually happens, is you try a new mouthpiece and sound different. That mouthpiece becomes the "perfect" mouthpiece, until such point as your ears become used to it and it no longer sounds different. At which point you become dissatisfied with your sound and the cycle repeats itself. You never really learnto play any of the pieces, because you're changing so often and you fall into the trap of believing that there's a mouthpiece out there somewhere, that will solve your problems for you.
Better, IMO, to find a good basic setup, (which you already have), and spend the time working on fundamentals and your ability to shape and control your sound. Then,you'll be in a far better position to evaluate other mouthpieces later, should you wish to. The biggest problem most of us have as novices, is trying to play pro setups way too soon. Being able to get a sound out of a wide open mouthpiece, and being able to play one, are two different things. The biggest improvment in my alto sound, came from going back to a Selmer soloist (fairly small opening), from a Jody Jazz (with quite a wide opening).
