Mario Maccaferri designed his Concert Model in the thirties. His challange was to make a classical guitar for the largest concert halls. As a concert player he knew the importance of a great playing guitar. The cutaway is very helpful to reach the highest notes.
For the classical repertoire the Nylon Gipsy didnít became very popular. Why? Maybe because the traditions in the classical guitar world were not ready for his futuristic technical genius.
Stiff back construction
Mario Maccaferri also used a sound box in this instrument for sound improvement. I donít see any advantage in the sound box. In my opinion the best result for the sound reflection is a very stiff back construction. I make the back extra stiff so there is no need for a extra sound box
For the top I use European spruce or cedar. The bracing is a traditional fan concept. For particular instruments I use 5 fan braces reinforced with a thin layer of carbon.
I prefer a slightly raised fingerboard for a comfortable neck angel. This also improves the sound.
The Nylon Gipsy is very popular for all kind of fingerstyle, acoustic jazz and Bossa Nova
