Only people that play guitar. ;D

History of the guitars:

The most popular and versatile instrument in the world originated from a Spanish musical instrument. The vihuela, as this instrument was called, originated by two other older instruments still: the 'ud, "with five strings, popular in the Middle East and the " Cozbi ", a musical instrument Roman. The guitar or classical guitar, appeared in Italy in 1970, and the electric guitar was an amendment to the actual guitar.

Electric guitars appeared in 1930. They generate a very gentle sound and bass, very different from what we know today. To increase the sound power of the instrument, they decided to put pickups, which functioned as microphones. This created a slight problem, as they did the bulges of the guitars vibrate, causing the famous sound change called "feedback ". To solve this problem, the famous Les Paul invented the solid body guitar, which left the instrument in the way we know it today.

Rickenbacker The company began manufacturing the first guitars in 1931. The first model of electric guitar to be marketed was the "Electro Spanish". However, the main responsibility for mass production and popularization of the instrument was Leo Fender, creator of the most traditional guitar manufacturer that bears his surname. Fender also developed the most legendary guitars, in the opinion of many: Fender Stratocaster.

The guitar became popular after World War II, in the 50 and 60, during which time he won big in the music space. Today, it is estimated that there are about 50 millions of players worldwide.
