I was asked to design a machine that would look somewhat like a good French machine. I came up with the "Peterson". Many of these machines have obviously gone to France, and I have seen them on old and new French instruments. I myself have used them on many occasions on "Hawks" basses. They have complimented the instruments well. They come with a screw and washer which must be used to hold the cog in place. They are named after "John Peterson" of California, U.S.A. A fine fellow, good maker and repairer, but most of all a good friend.
