To respond to bobsax, Clark Fobes doesn't focus on his low level inexpensive mouthpieces. I mean, he GIVES his low level pieces away. But if you've got the cash, his higher level mouthpieces are some of the best out there. My Eb, Bb/A, and Bass Clarinet mouthpieces are all his. I also use his Eb extension to help the sound and intonation. He's great, and so are his products. He is also a dealer of some pretty great equipement like the reedgeek, and reeds in general. I thank the universe for Clark Fobes.
