Our mouthpieces were developed with help from many popular L.A. recording artists. They are made by a machinist who makes parts for JPL and NASA, so we know every model is perfectly consistent. They are cut out of solid brass, then sent to us for final adjustments before being silver plated. Please contact us for more info.
