Francois Louis Spectruoso Medium Large Chamber Soprano Saxophone MouthpieceThe Spectruoso Medium Large or ML has an ogival, more traditional type of chamber. It offers quite the same advantages of dynamics with more separation in the spectrum between highs and lows. A more airy sound with a lot of bounce. The perfect mouthpiece for Hard Bop style. Reminiscent of the sound of the 1950s, playing with the efficiency of the best modern mouthpieces.
