Hobbyists in the 1920s used carbon button microphones attached to the bridge; however, these detected vibration from the bridge on top of the instrument, resulting in a weak signal.
Electric guitars were originally designed by acoustic guitar makers and instrument manufacturers.
In a small group, such as a power trio, one guitarist switches between both roles.
In larger rock and metal bands, there is often a rhythm guitarist and a lead guitarist.
There are several types of electric guitar, including the solid-body guitar, various types of hollow-body guitars, the six-string guitar (the most common type, usually tuned E, A, D, G, B, E, from lowest to highest strings), the seven-string guitar, which typically adds a low B string below the low E, and the twelve-string electric guitar, which has six pairs of strings.
Popular music and rock groups often use the electric guitar in two roles: as a rhythm guitar, which plays the chord sequence or progression and riffs and sets the beat (as part of a rhythm section), and as a lead guitar, which is used to perform instrumental melody lines, melodic instrumental fill passages, and solos.
Early electric guitar manufacturers include Rickenbacker in 1932; Dobro in 1933; National, Audio Vox and Volu-tone in 1934; Vega, Epiphone (Electrophone and Electar), and Gibson in 1935 and many others by 1936.
The first electrically amplified guitar was designed in 1931 by George Beauchamp, the general manager of the National Guitar Corporation, with Paul Barth, who was vice president.
Another early, substantially solid Spanish electric guitar, called the Electro Spanish, was marketed by the Rickenbacker guitar company in 1935 and made of Bakelite.
By 1936, the Slingerland company introduced a wooden solid-body electric model, the Slingerland Songster 401 (and a lap steel counterpart, the Songster 400).
In 1934, the company was renamed the Rickenbacker Electro Stringed Instrument Company.
In that year Beauchamp applied for a United States patent for an Electrical Stringed Musical Instrument and the patent was issued in 1937.
It served as a major component in the development of electric blues, rock and roll, rock music, heavy metal music and many other genres of music.
