Callet DT-10 Trumpet Mouthpiece
To quote the inimitable Jerry Callet, "I believe I have finally made the best trumpet mouthpiece in my career (after making about 2000 models -- it's true.) It produces the perfect, focused tone with much less blowing of air!! No mouthpiece ever had such a balanced and versatile character. It also keeps your embouchure in proper position in all registers from double pedal F# to above double high C."
