  A multi-scale fretboard employs different scales for each string, in this case 660 mm (25.98 in) for the low-E and 640 mm (25.20 in) for the high-E. The in-between scales are then derived by interpolating fret positions between low- and high-Es . This approach provides better balance throughout the tonal spectrum. This is thanks to the fact that lower frequencies benefit from a longer vibrating string-length and higher frequencies benefit from a shorter vibrating sting-length.
 The neck extends over the body creating a raised playing plane relative to the body plane, thus providing better access to the higher registers without the need of a cut-away. At the same time, this results in an ideal neck-to-body joint angle.
 It is a soundport on the side in a strategic position (upperbout) that has a double purpose.
 First of all he act like a monitor allowing the performer to have a direct feedback. The soundport has also an acoustic value.
 The instrument in this case functions like a pump: as the air comes out ofthe soundwhole it forms a column that prevents the outside air from entering. A second opening increase the process of compression and rarefaction.
 6 additional brass or silk and steel strings under the bridge, they can be mounted and tuned with an harpsicord key
 A resonator, made in spruce wood, is inserted up of the neck, for increase the resonance of the guitar and for amplify the sound of Diapasons and Kalimba
 To this are inserted many tuning forks with different tuning (for realize that I cut with different height as the notes I needed) , that can be played and produce a percussion sound similar glockenspiel.
 A Kalimba with different tongues (usually called lamellas) is fixed on the back of the neck, the tuning is in pentatonic mode, but can easily be changes according the composition. Normally I play it with the thumb of the right hand and produces a haunting, fluid percussive sound, tranquil and enchanting
 further modification to the guitar to add new sounds. I added two singing bows and two resting on a coffee table to be easily beatings, I'm writing for this new guitar a new fascinating composition named "SAMADHI".
FABIO RAGGHIANTI is the Italian luthier who built this guitar under my request, after I introduced many modify
