Vandoren’s Masters clarinet mouthpiece line has been expanded with the addition of the ‘13’ series which is pitched at A=440. Previously available in two distinct models, Vandoren has also added the CL6 model to the ‘13’ series as well as the standard A=442 series. The Masters line features a unique exterior shape and chamber design, allowing for a resonance and tone color unlike any other Vandoren mouthpiece. The CL6 is designed for clarinetists preferring a slightly more open mouthpiece.
