I build my guitars in one single quality and model. I construct approximately three instruments per year, for that very reason I apply all of my knowledge and art for these guitars to be the very best that I can make.
I construct the body by hand. I don’t use machines for this task. It is a very meticulous job that requires several hours to perfectly and precisely adjust the wood to the mold.
This way I’m able to accomplish exact symmetry in the body of the instrument.
To secure the top to the back, I use pins made out of cedar and pine wood. This improves the vibration of the top releasing in an independent way the different areas stimulated by the strings.
The top and the back are closed using string, reaching precise pressure at all contact points between the pins and the rings for a perfect hold.
The designs on the wood are accomplished by using different types of wood, contrasting with different inserts of nacre and wood to make every guitar a unique work of art.
The necks are made of cedar wood. This being a vital piece of the instrument since it requires stability and firmness, I always look for woods that assure me a lifespan of no less than 20 years meeting those specifications.
The insert of the neck that attaches to the body is made of dovetail.

CONSTRUCTION OF THE KELLER ROSETTE
This is the way I craft the rosettes for all of my instruments. It is a very laborious yet rewarding task.
The design is inspired by the “yarará” (rattlesnake), that inhabits the shores of the Paraná River that bathes my city, San Nicolás de los Arroyos. The audio of the video belongs to a recording made with a Keller Guitar executed by Sebastián Rodríguez.
