Got the Selmer Mouthpiece today and tried it immediately. You are a magician, Joe! You took a brand new mouthpiece from a wonderful company which would simply not play for me and turned it into one which moves effortlessly from the lowest to the highest notes. I actually can’t believe what you were able to do Talk about exceeding expectations! If you can accomplish what you did with a mouthpiece made by someone else I can’t wait to see what you can do with one of your own creations.Thank you, Joe. I am in awe!!
