The V16 Hard Rubber Baritone Mouthpieces are inspired by the sound of the greatest mouthpieces from the fifties to the present. The V16 mouthpiece blows easily and sounds great. These mouthpieces have great punch, yet maintain a smooth tone at any dynamic level. The V16 is available with 3 tip opening sizes: B5, B7, and B9. B5 is flexible in playing and application. B7 has the qualities of the V5 series B75 with the sound of the V16. B9 brings out the baritone's power. Vandoren JAVA, V16 and ZZ reeds are recommended for these mouthpieces.
