The JDX Baritone sax mouthpiece is brighter and has a stronger projection than the Rousseau Studio Jazz Series. The JDX features a unique wedged baffle that 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 for sensitive ballad work. Comes with Rovner Ligature and Cap.
