Do you think that some mouthpieces just work really well with a horn? I have a friend that plays an Olds Recording and he uses a Schilke 14a4a with it. He swears by this combo, so I suggest it to one of my friends that plays a recording today. I had a nice Schilke 14a4a and I gave it to him for his 6a4a. He keeps emailing me telling me how good of a combo it is. My Yamaha matches with my MF III and my new 6a4a a lot, great sound and great combo. Do any of you think that some mouthpieces work with other horns this well? I am interested to hear if you have found a mouthpiece that works great with your horn.
