I have been using a Dukoff D8 tenor mouthpiece for years. I started using it because that's what was sitting on the shelf in the Army Band supply closet when I got there. Let me preface this by admitting that I know absolutely NOTHING about tip facing or any other tech talk regarding mouthpieces. What I DO know is that I LOVE the tone I get out of it. I use a Vandoren V-16 #3 reed. Problem is that it's just so darn hard to play a nice long phrase without running out of air. Also from low E on down, it's hard to get the notes out. Any suggestions on an alternate mouthpiece? Thanks!
