The True Temperament Fretting System is a revolutionary new way to construct guitar fingerboards. Super-accurate intonation over the whole fingerboard, without affecting playability. Chords ring sweeter, louder and longer. True Temperament have in 2019 launched a new generation of guitar frets. The frets, manufactured in Sweden by hi-tech company Trestad Laser AB, are made of stainless steel for a better sustain and durability. The True Temperament new fret design are developed to reduce slotting/fretting assembly time, and to present a high finish installment result with minimal after processing.
