This profile features precise open-string offsets designed specifically for guitars equipped with the curved, squiggly True Temperament fretting system. It accounts for string tension, mass, and fret geometries to deliver near-perfect intonation across the entire fretboard.
A needle answers "what is the average pitch right now?" A multi-harmonic strobe adds an extra layer to the tuning visualization by showing several harmonics at once, so you can fine-tune more confidently to fractions of a cent.
