Just Intonation Tuning System for Guitars

The Just Intonation Tuning System for Guitars is based on a set of fretboard models, designed to be interchangeable and combinable. As the name suggests, an interchangeable fretboard is not glued to the guitar neck, but simply held in place by an anchoring and magnetizing system, enabling it to be changed in seconds to access a new fret configuration. Some twenty musical scales in just intonation are available. Once transposed, these scales generate over a hundred different fret patterns.

Projections libérantes is a non-profit organization. In collaboration with L’école-atelier Lutherie-Guitare Bruand, we have developed this lutherie project for purely artistic and educational purposes, with no intention of commercialization. To build a guitar in just intonation, we recommend that you consult a luthier or order materials from specialized companies such as MicroTone Guitars (for interchangeable fretboard) or Adjustable Microtonal Guitar (for movable frets).
