Electric bass guitars are bass guitars that use electricity to produce sound. The first electric bass guitar was built in 1931 by George Beauchamp, the general manager of the National Guitar Corporation. Beauchamp built a prototype from a custom-made wood cabinet and a Fender Precision Bass guitar. The prototype featured a single pickup, but it was not until 1934 that the first production electric bass was made. The electric bass guitar became popular in the 1950s and 1960s, when jazz bassists began to use it in fusion and rock music. The electric bass guitar has since become an important part of popular music, and is used in a variety of genres. The electric bass guitar is similar in appearance to the acoustic bass guitar, but it is larger and has a lower sound output. The electric bass guitar is played using the same techniques as the acoustic bass guitar, but it is amplified using an electric amplifier. The electric bass guitar can be played solo or in a band setting. It is an important part of many genres of music, including jazz, blues, funk, rock, and pop.
