Acoustic Hollow Body Flamenco guitar
Spruce top, cypress side and back, mahogany neck
Since flamenco musicians were often poor, traditionally cheaper wood, such as cypress, was used for the sides and back of the instruments. Cypress is lighter than rosewood and also provides an earthy sound. Because this type of wood is very strong, it can also be processed thinly. This property and the light weight ensure the sharp flamenco sound. Spruce was usually used for the soundboard because it provides a clear sound.
Hernández added an innovative, sloping bar under the body, giving the guitar a more powerful tone.
