The Morgan Classical Bb Clarinet Mouthpiece represents a return to the principles of acoustical designs and handcrafting methods used for well over 100 years. Morgan is confident that the mouthpiece performs better than mass-production machine-work processed clarinet mouthpieces. Morgan products are hand-crafted from raw rubber castings made in Morgan"s own molds, from the finest European rubber. Instead of the machinery normally used in a mouthpiece factory, only hand tools are used to produce a fine Morgan mouthpiece. The only machine used is a buffing wheel for polishing the surfaces. All Morgan mouthpieces are expertly hand-faced to an accuracy of .0002", or 1/15th the thickness of a piece of paper, and that"s why Morgan mouthpieces really perform. Only a few years ago the first Morgan clarinet mouthpieces were produced, and now many hundreds of the finest players in the world use Morgan clarinet mouthpieces as their mouthpiece of choice.Classical Bb clarinet mouthpiece Expertly handcrafted Accurate to .0002"
