I'm wondering if anyone can help me with some Monette mouthpiece info: I recently bought a Monette Prana mouthpiece which I've been told was designed for John Chudoba. It's a dynamite mouthpiece, and even though the dealer coudn't give me the specs buying it was a no-brainer. However, every time I write to Monette to try to find out the actual specs, they say, "It was custom designed for John Chudoba...yadda,yadda,yadda... if you'd like more info, write us..." So, I write them and never hear from them again. After several attempts, including Dave Monette's Facebook page, it's getting a bit annoying! I'd just like to find out the rim, cup, backbore numbers etc. if possible. The markings on the mouthpiece say: JC V2 84 and down on the shaft is stamped 23. If anyone knows what these mean, I'd greatly appreciate it!
