An ELECTRIC GUITAR is a guitar that
uses a pickup to convert the vibration of its strings into electrical
impulses. The most common guitar pickup uses the principle of direct electromagnetic
induction. The signal generated by an electric guitar is too weak to drive
a loudspeaker, so it is amplified before sending it to a
loudspeaker. Since the output of an electric guitar is an electric signal, the
signal may easily be altered using electronic circuits to add "color"
to the sound. Often the signal is modified usingeffects such as reverb and distortion.
Invented
in 1931, the electric guitar became a necessity as jazz musicians
sought to amplify their sound in the big band format. During the
1950s and 1960s, the electric guitar became the most important instrument
in pop music. It has evolved into a stringed musical instrument that is capable
of a multitude of sounds and styles. It served as a major component in the
development of rock and roll and many other genres of music.
