I got he mouthpiece today. All I can say is : this is crazy!!! How can one mouthpiece be that good and make so much of a difference ? This is like a different horn now, the piece really brings out the quality of the Keilwerth and gives everything I asked for, and more. Intonation, warmth, sound “complexity”, great articulation, easy to blow and is so flexible, Just enough edge when pushed … I could go on and on but you get the idea. I can get the kind of sound we discussed. How do you do it? No wonder the Missing Link has got such great reviews. Thanks a million.
