The sound of this mouthpiece is reminiscent of the John Coltrane album “Crescent" circa 1963. It features a slightly smaller tip opening (6*) than other models. It had a large bore and a slight baffle. End of 80ies Dave designed for PMS a Crescent model with a little larger bore for the dark Bebop sound.
