As a type of musical instrument, the jazz guitar is a special type of guitar that differs in construction (and sound) from the Classical Guitar and the Electric Guitar.
The Jazz Guitar originated in the 1930s, when guitarists performing in Big Bands needed an instrument capable of producing enough sound to perform solo lines in a large ensemble. The breakthrough occurred with the introduction of electric guitar amplifiers, which provided extra sound volume.
The Jazz Guitar is therefore a type of electric guitar. Traditionally, jazz guitars feature an archtop body with a large hollow soundbox and f-shaped sound holes. The typical jazz guitar uses steel strings, a floating bridge, and two humbucker pickups.
