Kay Musical Instrument Company was a musical instrument manufacturer of the United States, in operation since the 1930s until the 1960s.
 It was established in 1931 at Chicago, Illinois by Henry Kay Kuhrmeyer, from the assets of the former Stromberg-Voisinet, which was founded as Groeschel Mandolin Company in 1890.
 Kay offered their first electric guitar in 1936—five years after the Rickenbacker "Frying pan", and the same year as the Gibson ES-150.
 Nonetheless, Kay is considered an "electric guitar pioneer" because Kuhrmeyer bought their past company, Stromberg-Voisinet, and produced the first commercial electric guitar, the "Stromberg Electro", in 1928.
Robert Lee "Bob" Dunn (February 5, 1908 - May 27, 1971) was an American jazz trombonist and a pioneer Western swing steel guitarist.
 Although much influenced by influential, key Hawaiian lap steel guitar player Sol Hoʻopiʻi, Dunn played in his own original bluesy style and was the first to record an electric guitar, preceding other country & western guitarists following him shortly.
 He preceded by over three years George Barnes (with Big Bill Broonzy in 1938), Leonard Ware and, slightly later, Eddie Durham.
Charles Henry Christian (July 29, 1916 – March 2, 1942) was an American swing and jazz guitarist.
An electric guitar is a fretted stringed instrument with a neck and body that uses a pickup to convert the vibration of its strings into electrical signals.
 The vibration occurs when a guitarist strums, plucks, fingerpicks, or taps the strings.
 It is sensed by a pickup, most commonly by a magnetic pickup that uses the principle of direct electromagnetic induction.
 The signal generated by an electric guitar is too weak to drive a loudspeaker, so it is plugged into a guitar amplifier before being sent to a loudspeaker, which makes a sound loud enough to hear.
 The output of an electric guitar is an electric signal, and the signal can easily be altered by electronic circuits to add "color" to the sound or change the sound.
 Often the signal is modified using effects such as reverb and distortion and "overdrive", with the growling sound of the latter being a key element of the sound of the electric guitar as it is used in blues and rock music.
George Van Eps (August 7, 1913 – November 29, 1998) (often called the Father of the Seven-String Guitar) was an American swing and mainstream jazz guitarist.

 He made the first commercial recording of an electric guitar on March 1, 1938, in sessions with Big Bill Broonzy.

Dorlis (born February 23, 1982) is the stage name for a Japanese musician from Okayama, Okayama Prefecture.
 She started out in classical guitar, but at about age 17 became a street musician and dropped out of high school.
 In time, she became a jazz and swing musician.
 Her music has at times been deemed nostalgic because of its Swing Revival style.
 This makes her work somewhat analogous to American swing revivalists like The Brian Setzer Orchestra or Big Bad Voodoo Daddy, though stylistically it is more similar to 1920s and 1930s swing jazz such as Django Reinhardt's.
 She is primarily a jazz singer, though also is a guitarist.
 She is signed with Avex Group's Rhythm Zone sublabel.
 She used to be connected with Victor Entertainment.
