This is an original Otto Link Florida USA 6 tenor saxophone mouthpiece. Its tip opening measures at 0.091. This piece is pretty much exactly what everybody is looking for in a tenor mouthpiece. It responds effortlessly, has plenty of volume, takes air well, like a larger tip piece, but is more comfortable so you can play it longer than a bigger tip. These pieces are in high demand since there really isn’t anything that has “that sound” like a good Florida Link.
