Hey everyone, I just wanted to see who all plays with these mouthpieces or has played with these mouthpieces, get your opinions on it, the usual stuff. I have one and I enjoy playing on it, I believe it gets a more focused sound that my Conn Helleberg that I own, I also use a PT-88 for big stuff, my instrument is a 1970s Miraphone 186 CC 5 valve tuba. The warburton has a very focused sound, and can also hold together in louder volumes throughout the range of the horn, esp. in the low register. I like very much so, and alternative if ya want the Helleberg feel, but a better focused sound.

How do these differ from the ones labeled "Canadian Brass" or the ones that Brian F used to sell? Aren't they all made by Terry Warburton?
