Well, these are the Iconic large chamber classic jazz mouthpieces. Everyone from Benny Golson, Charlie Rouse, John Coltrane made their signature tones on these. They cover many album covers from the 1940’s to the 1960’s and beyond with good reason. This one is a 5* and shows plating wear but structurally in great condition with original ligature and somewhat crushed cap. This has a buzzy woody and big-low-end sound.
