- Inner Diameter: .680 measured .04 inches into the cup.
- Outer Diameter: 1.134
- Cup Depth: This mouthpiece has an MDV (Medium Deep V) cup, which is similar to a Bach 1 1/2 C or 5C, Warburton MD, regular Schilke, or Yamaha C cup, but it has a slightly more V shaped transition into the throat. This cup produces a large, dark orchestral sound, which is made a little darker than the MD cup by the extra V shape.
- Backbore: This mouthpiece comes on a Medium-Large backbore.
