Thomas Bacon Signature Series This mouthpiece has a wide inner rim diameter with a large V shaped cup. Tom requires an extremely versatile mouthpiece because he plays in so many different settings: large symphony orchestras, small chamber ensembles, brass groups, and in solo recitals. With this mouthpiece he can play as high or strong as is necessary, and yet can create as rich and full a sound as he wants in any register. The sound is well focused for clarity and projection, and the playability is responsive and comfortable. | Specifications | | Model | Inner Diameter | Contour | Thickness | Cup Depth | Throat | Backbore | | YAC BACON | 17.99 mm | standard | medium | semi-shallow (V cup) | 4.5 mm | semi wide | Canadian Brass Horn Signature Series DISCONTINUED Chris Cooper prefers this fairly large inner rim with 'V' shaped cup as it helps him create the many tonal colors he needs for the varied repertoire of the Brass: soft and mellow, rich and dark, strong and brassy.
