Patrick 5Z Doc Severinsen Model Trumpet Mouthpiece The following is quoted from Net-Brass: -------------------------------------------------- This is a mouthpiece made by Steve Patrick, a studio and freelance player. The trumpet division has branched out from the previous LOUD brand. This model was developed based on the model used by Doc Severinsen, a superstar in the trumpet world, in the 1970s. The inner rim diameter is slightly smaller than a Bach 10-1/2. The rim is flat and slightly thicker. The outer rim diameter feels about the same as a Bach 10-1/2. The inner edge of the rim is scooped, making it difficult for the lips to touch the inner wall of the cup, and designed to reduce fatigue. The cup is a gentle UV cup. The depth is slightly deeper than a Bach 10-1/2C. The throat is slightly narrower than a #28 (3.57mm). The backbore is between a Warburton 4 and 5. This mouthpiece is designed to easily produce a rich, full mid-low range and brilliant high notes. When played gently, it produces a warm sound, and when more air is put in, it produces a core-filled, brilliant sound. It produces a dense, focused sound. It is a design that allows for a wide range of expression. *One-piece type. -------------------------------------------------- There are some minor scratches on the shank due to use, but there are no major scratches, dents, or plating wear that would interfere with playing. This is a used item, so please refrain from purchasing if you are sensitive or concerned about this.
