Through the recovery and restoration of historical string instruments, the lutier Daniel Gil de Avalle contributes to the study and recovery of Spanish heritage and culture.

The process of construction of professional Spanish guitars and concert begins with the selection of high quality wood from different parts of the world: Palo Santo, Madagascar, Cypress, Fir, Cedar, Ebony, Maple, etc. The wood dries naturally between 10 and 30 years according to the model of the guitar, to ensure the maximum harmonic splendor of the guitar. During the construction process of these Spanish guitars, natural tails are used to provide the instrument with the necessary closing and tension. The guitar is varnished by hand, using Goma Laca so that the guitars acquire the maximum response given the elasticity of this varnish.
