Wayne: "The FD model has a very intimate, dark sound. I’ve used this for several different solos that needed to be more cornet-like in nature. The FD is also a great tool for achieving an airy and diffused sound (ala Chet Baker). I absolutely love this mouthpiece! Forget your flugelhorn; pop in the FD, and you won't need to check an extra bag when traveling. The FD uses the same rim found on the other WB Models."
