Holy holy f… holy sh.. Joe! Thank you thank you thank you! I only got to noodle with it for half an hour before I headed into my day, but what a miracle. All my joy at playing has returned. What an easy blowing but full sounding mouthpiece. I didn’t realize that a mouthpiece could make or break it all. I have a Leibman Keilwerth SX90 and a Muriat System 76 and both sound and play amazing on the full range of the horn. The mouthpiece you made helps players leap to the next level. Wow.
