Micro frets had several patents, and the most notable were for a fully adjustable metal nut. There's a section for each string, with adjustments for height and compensation - distance from the first fret. These patents held the concepts used by Buzz Feiten and Earvana for fine-tuning intonation.

 The Signature used a two-piece chambered body, so they are very light and resonant. The neck is maple, with a rosewood fingerboard .

Guitar players like Carl Perkins and Mark Farner of Grand Funk Railroad used Micro Frets and Martin Gore of Depeche Mode. Genesis' Mike Rutherford converted a Micro-Frets Voyager into a 6-string bass.They closed following the death of its founder, Ralph Jones in 1969.
