Kanstul Trumpet Mouthpiece M-B7F Also for sale on other sites, so don't delay! Priced at Mercari price. This is a Kanstul mouthpiece produced using digital scanning and computer-controlled grinding machines. This model is based on the popular Monette STC-1 B7F, the same model used by Art Farmer and Greg Adams of Tower of Power. The "F" in B7F is taken from Farmer. Weight is 118g. The inner rim diameter is slightly smaller than a Bach 5. The rim is flatter and slightly thicker than a Bach 7B. It has a soft rim design. The outer rim diameter feels like it's between a Bach 3 and 5. The inner rim edge is somewhat distinct. The cup is a slightly shallow V-cup, with a depth similar to a Bach D. Due to the V-cup, the shoulder angle leading from the cup to the throat is clear. The throat is about #21 (4.04mm). The throat has a long straight section, designed for stable high range. The backbore is similar to a Warburton 5. The shank end thickness is about 0.9mm, which is slightly thick. It produces a sound that is thicker and more powerful than the Monette B7F. When played softly, it has a warm sound, and when you put air into it, it becomes a brilliant sound with a core. It's a design that allows for a wide range of expression. It's an all-around mouthpiece that can be used from solo to big band to horn sections. #TrumpetMouthpiece #Kanstul #Monette #BigBand #ArtFarmer #GregAdams #STC-1 B7F #M-B7F
