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 |
