Today we made an Osmun Bb Mouthpipe for a Kanstul Piccolo Trumpet. This is a pipe we do not normally stock, but can make up anytime. Like most of the Osmun Piccolo Trumpet Mouthpipes, you can move slightly more air through the pipe and into the horn, making the blow feel more trumpet-like. Also, you can move away from the lighter “toy trumpet” sound much more easily with our pipes. An easier blow with less back pressure usually leads to greater endurance.
