This is the Core for tenor saxophone by the Saxquest line of mouthpieces. “The Core” was designed by James Bunte. Its aptly named as its core sound is what sets this piece apart from all others. Moving slightly on the darker side of the sound spectrum, it harbors all of the harmonic complexity of the Great Neck era hard rubber Brilharts blended with the ease of play and clear projection of a classic Link.
James personally faces each of these mouthpieces and takes them through an exhaustive play test regiment.
