I am not necessarily looking to buy a new mouthpiece, and I don't buy hard rubber pieces anyway, irrespective of the level of sympathy I have for those who manufacture them. I think I have some basic understanding of common mouthpiece designs, but the Reso Chamber appears to be rather distinct from other Links, and just about any other mouthpiece out there. The replies in this thread help to reduce the mystique somewhat, and I appreciate them irrespectively of underlying intent if any.
A few years ago, I would indeed just have bought a piece to figure out what it was all about, but those days are gone. It yielded a pile of mouthpieces that were hard to sell, certainly with my - approaching zero - level of salesmanship.
My reasons for starting this thread were (a) curiosity and (b) an everlasting struggle with trying to figure out whether to embrace or fight what appears to be my inherently darkish tone on tenor. The latter is hardly of general interest.
