We feel that, on guitars with traditional straight frets, the Buzz Feiten system offers a genuine and worthwhile improvement in chord consonance over standard intonation. However the improvement is limited, because you can only do so much with one tiny adjustment to the position of the nut and a little stretch tuning – you are trying to calibrate 132 fretted notes (on a 22-fret guitar) with only 7 adjustments (nut position + 6 offsets to the intonation points at the bridge). In common with other systems using nut compensation (either overall compensation, or individual compensation for each string) and “offsets” in the octave intonation, it is a compromise solution, albeit a better compromise than traditional intonation.
TRUE TEMPERAMENT™ calibrates each of those 132 fretted notes *individually*. No compromises.
