This Miami Dukoff D5 alto saxophone mouthpiece measures .076, so like a Meyer 6 tip. The rails have some dings in them, but it still plays fine. I could clean it up pre-sale. Up to you. If you want a bright, cutting, smooth jazz/commercial alto sound, this will do the trick. I’m trying to make it through the description without mentioning a certain player. Looks like I succeeded. Straight sidewalls, small-medium chamber, and high stepped baffle, tip opening measures 0.076″. The super power chamber is truth in advertising. Awesome projection, low resistance, bright tone.
