Used Austin Custom Brass H3S trumpet mouthpiece

The ACB H3S is modeled after a vintage Heim trumpet mouthpiece with some modernizations. The rim has a semi-flat contour and the inner diameter of a 3C. The cup is a medium-deep V-shape which gives the mouthpiece a rich tone excellent for jazz. The blank is ACB's "vintage" blank which resembles the original Heim blank.
