This mouthpiece was created through the magic of “what if…”. What if we took a Bill Chase rim and put it with a Cat Anderson cup? Voila! May we present the Legends Bill Cat. The .625″ inside diameter rim is round and comfortable (just like the BC Master), and the cup is a very shallow bowl (just like the Cat Master). Put that together with the somewhat tight #30 throat and the Legends Manhattan (very focused) backbore and you’ve got a mouthpiece that is really the cat’s meow! It’s a great piece for a commercial or lead player who likes an inside diameter that’s not too small, but doesn’t want to “pussyfoot” around the upper register.
