B-Stock, Rousseau JDX6 mouthpiece for tenor saxophone; tip opening: .105"; brighter sound and stronger projection than the Rousseau Studio Jazz Series; 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; full-sounding mouthpiece, with enough edge to “cut through” but enough warmth for sensitive ballad work, B-Stock with full warranty, may have traces of use.
