The lattice has proved t be one of the most efficient bracings for a concert classical guitar. The system allows the builder to use otherwise impossible measures during the reduction process of the top. These measure make it possible for the top to push a lot more air and this translates in a bigger sound. The type of sound is also unique. A much richer palette of mid high tones becomes available to the performer. T summarize it, Willims' sound since 1985 is a lattice braced sound. I like the sound of my lattice better because I use wood exclusively in the construction and no synthetic materials (carbon fiber et.) which deliver a type of "plastic overtone'' to the sound and make the expansion/contraction of the woods a much less reliable one. Add to that that I incorporate a violin tie, and all the anchoring work is moved to a much sturdier part of he guitar allowing the instrument to vibrate FULLY, the top of its possibilities.  (Williams He played a Hauser -Fleta- braced in all his previous recording and concerts).
The marvelous set of Brazilian rosewood resembled the peak of an Himalayan mountain and I HAD TO call her " Everest". She stands at the highest pinnacle of sound and the similitude was a natural. I matched her with a perfect set Alpine spruce top and decided to embellish her with a handmade Mother of pearl master worked rosette. The ebony armrest, violin tie, bridge  and bindings along with the radiused ebony fingerboard, make her lines stand out in beauty and luxury. I used Galilei's Saltarello to show the amazing lung on this babe. The bass pedal delivers with the strength of a locomotive while the trebles draw the most brilliant melody.  A great separation of voices which is the trademark of lattice bracing. I stress the fact that I do not use the rest stroke in and this talks of a master singing instrument. 

Radiused or flat fingerboard?
The radiused fingerboard has been around the acoustic and the electric guitar since day one. The same is true for most instruments of the Stringed family of instruments (violas, violins cellos, bass). Radiusing (image above) makes barre and left hand stopping A LOT easier. The only drawback is that you will NEVER want to play a  flat fingerboard after that. If you are having your custom guitar built, I am all pro radiusing the fingerboard.  The standard fingerboard is flat.

The hand embossed leather case is a work of art on its own right. Built by one of a handful of very talented leather embossers in Latin America. 
Its built following my specifications for the interior to fit Bellucci guitars like a glove. All Plush interior, key and accessories compartment.

640mm or 650 mm?
Regarding 650mm or 640 mm fingerboard fret spacing, keep the following rule at hand: If the distance between the tip of your thumb and the tip of your little finger is equal or less than 9 in. when fully stretched, use 640 mm. Adapting from one scale to the other takes no adaptation
