For use with any brass instrument - trumpet, cornet, french horn, trombone, baritone, euphonium, tuba, sousaphone and more. Solid one-piece design will last forever. Used by professional repair techs everywhere (including ours) and available to you as well. Simple and safe to operate. Will not damage your horn or mouthpiece when used properly. An excellent addition to any school or music studio. More reliable, easier to use and gentler on the horn than other systems in use. Also known as "The Tiger."
