The DEG Mouthpiece Trueing Tool removes dents in the shank of all brass mouthpieces, from French horn to tuba with just a twist. The trueing tool is precision made from stainless steel with a T-handle for easy grip.
Minerals from saliva will build up on both the inside and outside of your mouthpiece and dead skin cells from lips and tiny food particles will dry on the inside to form hard to remove deposits that will grow smelly bacteria and mold.
