The adjustments you made are perfect . I am now able to pop out all the top end notes without shutting down. It’s great. Thanks for knowing what questions to ask and what adjustments to make. I am very pleased with the sound and playability of my Missing Link. I appreciate your craftsmanship, Joe .If you ever decide to design an similar Alto mouthpiece, please let me know. I’ll be sure to refer others to SopranoPlanet. Thanks again.
