All fecal material aside, I don't have any direct experience of said piece, but you can get some info at lambersonmouthpiece.com. Same thing happened to me on a couple of mouthpiece posts, so you're not alone...

Mactenor, that's hilarious! I used to play an L7 wood tenor piece that I loved for a while....really rich sound but also very powerful. it started to not respond as well as I wanted it to, I don't know, maybe it was the fact that it was a wood mouthpiece and they can be unstable, or maybe the Morgan excalibur I had been playing at the time was just the right piece for me at that time, but I sold the L7. I'd love to get my hands on another one but this time in hard rubber, and used so I don't have to shell out the big bucks.
