Have you ever wanted to sound like another musician, gotten an identical set-up to them, but then noticed you still sound nothing like them? Simply copying another person's set-up is not very effective because there are other important factors that come into play like to blowing style, interior mouth shape, abdominal pressure, and embouchure.  These other factors can all impact the sound you create on the saxophone.  Adjusting the baffle on your mouthpiece can make a significant difference in your sound and that might help you overcome the other factors above. The baffle is truly the most magical and interesting part of the entire saxophone/mouthpiece combination.
