In celebration of its 50th anniversary, Rousseau Mouthpieces has introduced its ER50 Series mouthpieces. These are the first new Rousseau mouthpiece models to be introduced in almost a decade. The ER50 series features two new alto saxophone models: the ER50 Classic and the ER50 Custom. Both new models are completely made at the JodyJazz factory in Savannah, Georgia. The Rousseau ER50 Classic alto saxophone mouthpiece is designed to give increased projection and freedom while the Rousseau ER50 Custom alto saxophone mouthpiece provides focus without restriction, letting players achieve a flexible sound with great warmth and shimmering tone color.
