The Drozdoff flugel mouthpiece has the same rim as his Classic 3-7 DOC mouthpiece with a deep DOC FLX cup. 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. One piece flugelhorn mouthpieces are available with a Standard (American, Yamaha) or Bach shank.
