The Rovner Dark has evolved since its introduction in 1974 to take full advantage of Rovner’s patented elements, adding even greater resonance. The Dark is a superb generalist, providing a dark, warm, centered tone. The “go to” for music educators for its reliability, easy installation, durability and performance, it has also long been enjoyed by professional musicians the world over. Available in two dozen sizes, there’s a Rovner Dark to fit most any mouthpiece.
