The Pierobon Lead is one of the signature mouthpieces of Wedge endorsing artist Marco Pierobon of the Gomalan Brass. The Pierobon Lead has an OD of 1.198 inches and an ID of .662". It is similar in size and depth to a Yamaha 14A4A. This mouthpiece has a very comfortable Gabriel style rim with a lateral dip of 15/1000". The Pierobon Lead incorporates our new DOC (double oval cup) that carries the oval rim shape into the base of the cup. Wedge plastic mouthpieces are machined from black Delrin just like our brass and stainless steel models. They have all the advantages of a metal Wedge mouthpiece, the main difference being that they play with a darker sound. Slotting and response is excellent. A 25 throat is standard on these plastic models.
