The best guitars come from trees about 800 years old. Trees with enough rings in their trunks, to provide wood with a tight and straight green. Wood flexible enough to vibrate yet strong enough to withstand the pull of the guitar strings. The guitar traveled from North Africa to Europe with the more so invaded Spain in the eighth century. In time the guitar became the signature instrument of Spanish flamenco music, and the trademark of the singing cowboy. In the nineteen thirties the acoustic guitar debuted as a jazz instrument. By the nineteen sixties as the electric guitar took over rock and roll, the acoustic guitar remained a staple of the folk music scene.

The size of a sound hole affects how the guitar will sound, the larger the hole the more trouble, the smaller the hole the more base.
Then they glue on a wood inlay decoration called a rosette. Next they make the sides of the guitar, they first emerged wood pieces in boiling water for about 15 seconds. Then place them in a heated press to make the curve. The press applies heat from both the top and the bottom for about a minute, then they connect the two sides with blocks of wood made of either mahogany or popular. One is glued and clamped at the bottom, the other at the top. Then they glue on and clamp a wooden lining which will connect the sides to the top and back. Those little cuts give it flexibility around the curves. Then with a hand router they carefully notch the lining, to receive four wooden braces to support the back of the guitar. Strategically placed braces help the top of the guitar withstand the tension of the strings, they also equalize sound frequencies by controlling vibration differently at different spots. After a vacuum press makes the bracing it here evenly, they glue on the top and bottom. The body of the guitar is now assemble, it goes into a press than a drying rack for several hours. Next they glue on a plastic binding to protect the guitars edges. Then comes a fine sanding, next a machine with a special sensor measures the precise angle at which the body and neck of the guitar will later be attached. The angle is critical for sound quality it drills the holes and sans the pieces accordingly.

Then they glue on the head stock not, a hard plastic piece that spaces the strings evenly. Next comes the saddle, then the bridge pins which lock the strings in the bridge. Finally they string the guitar using an electric winder because of all the blue drying time it takes three weeks to make a guitar. The wood will become subtler the more the guitar is play so as the guitar ages the better it will sound.
