Rousseau Jazz Model JDX6 Tenor Sax Mouthpiece
This mouthpiece is unique in that it was something of a roller coaster baffle. Starts high right behind the tip, dips down into a little “lake”, rises back up again and then drops down into the chamber. I think I was able to capture it in the photos. The sales literature calls it a “wedged baffle” and goes further to say, “…balances a stable sound with greater power, edge and projection. Good response and an even scale in all registers. A full sounding mouthpiece, with enough edge to “cut through” but enough warmth is for sensitive ballad work.”
I measure the tip opening of this JDX6 at a surprising 0.109″. Surprising because I assumed that a “6” would be more like 0.090″, but I guess that is an arbitrary scale. Looking it up, it says it has a 2.67mm tip opening which I convert to 0.105″ The facing length is longer at 29mm…allows more of the reed to vibrate, though you might have to change the stiffness of reed accordingly.
