One of our "Guitarras Calliope" Luthier Models Orfeo was sent to "True Temperament" in Sweden and came back with another fretting system for accurate intonation. John Mc Laughlin and several other guitarists use this fretting system. More Infos: http://www.truetemperament.com/site/index.php
We deliver fretless guitars, but they will be sent by the owner to Sweden at own risk.
