We will make your old mouthpiece to exact specifications. We copy the whole works, the internal and external parts of the mouthpiece. The mouthpiece you receive will be an exact duplicate of your current mouthpiece. This process is much more involved because of Knurling and the custom made tooling for back bores etc. Depending on tooling needs and fabrication allow 2-16 weeks depending on what tooling we have to make in house for your new mouthpiece.
