Model




I build my guitars with the highest quality standards. I complete around three instruments per year, which is why I put all my knowledge and artistry into making each one the best guitar I can possibly build.

Over the years, I have refined the soundbox towards a more Spanish, classical design—also aiming for greater responsiveness in a slightly smaller top than in previous models. Enhancing both aesthetics and power.

The new model features an elevated neck, mounted over the soundboard. This improves comfort, power, and performance, while also providing greater stability by allowing the natural contractions of the fingerboard to act on the neck rather than the top.
The soundboard design is influenced by Torres, Friederich, and Romanillos.

Exercising as a guitar teacher has given me the experience to give an identity to the sound of my instruments. It is wide and powerful, with a remarkable balance between its fast attack bass and crystal clear highs.

Comfort to play thanks to the perfect calibration of the height of the strings. Most notable is the great timbral range that can be achieved with the right hand, which together with all its qualities make it an excellent instrument for expression.

The usual measurements are: Shot 650 mm. Fingerboard measurements are 52mm on top and 62mm on fret No. 12. Handle width 23mm. Distance between strings in the bone of 8.5 mm. Distance between strings on the bridge of 11.8 mm. 20 frets of German nickel silver in 2 mm. Tuning and changes according to the instrumentalist.

The finish is lacquer rubber, because it has less resistance to vibration than other industrial lacquers. This, being a natural product, is better absorbed by the wood and gives a superior finish highlighting the grain, more so when done in the mirror.
The rosette is handmade in an artisanal way. Its mosaics form the back of the "yarará", native to the coasts and estuaries of the Paraná and bears the stamp of the place where I live. It is a very laborious job and takes several days to complete. But it is the signature of the luthier and it is how my guitars are identified. Everything they represent is worth the effort. From this invoice comes a work of art and personal.
