Don't have the exact specs... but in general terms: The cup is fairly shallow & bowl shaped; the diameter is fairly wide, as is the rim; the venturi is fairly small; but the backbore is rather large. My favorite mouthpiece for my Mirafones (184 & 185, both in CC). Seems to work the best on smaller German style tubas. Rumour has it that Roger Bobo had a hand in designing it.
