 Although he subsequently studied with several well known and accomplished trumpet instructors in the Pittsburgh area and dedicated himself laboriously to mastering the instrument, by the age of thirty Callet could still not play a high C. In 1947, after many years of struggle, Callet began researching the physical elements necessary to develop a “Super Power Embouchure”, such as those developed by players such as Harry James, Charlie Shavers, Horst Fischer, Maurice Andre, and Maynard Ferguson.In 1970, at the age of 40, and after much trial and error, Callet had developed his new embouchure, and named it Superchops.The Superchops embouchure methodology eventually led him on the quest to design and produce the best trumpets and mouthpieces available.
