The Pierobon Cornet mouthpiece is the signature cornet mouthpiece of Marco Pierobon of the Gomalan Brass. The diameter is slightly smaller in diameter than a Bach 5C with a wide Gabriel style rim. The rim has an ID of .662 and an OD of 1.12. The lateral dip is 15/1000". This is the same rim found on the Pierobon C, Lead and Pierobon Flugel. The cup is the depth of a Wick B an throat is #19.
This mouthpiece has our new Double Oval Cup (DOC). The diameter of the rim and cup in the vertical dimension is 10/1000 of an inch larger than it is from side to side. This means that the oval shape of the Wedge rim is continued down to the base of the cup where it joins the throat. The DOC design, found only in Wedge mouthpieces, provides the added efficiency of a smaller mouthpiece with the big sound, clear attacks, and flexibility of the larger mouthpiece.
