The Ridenour Encore Bb clarinet mouthpiece offers the excellence of a handmade mouthpiece to the young and advancing clarinetist at an amazingly affordable price. Made from a blend of hard rubber and DuPont acrylic specifically formulated for woodwind mouthpieces, the material produces a deep, dark sound that significantly reduces brightness of higher tones. Unlike pure hard rubber mouthpieces, the Encore will not discolor, oxidize, or leak sulfur.
