The ESP is a 24kt Gold Plated Metal Saxophone Mouthpiece. The removable baffle with its 24kt Gold-plated secondary
reed makes the ESP one of the most versatile mouthpieces in
the world. Dark, lush and warm without the baffle, this metal sax mouthpiece
is brighter, louder and still warm with it. If you can think of it,
the ESP can play it.
