The electric mandolin is an instrument tuned and played as the mandolin and amplified in similar fashion to an electric guitar. As with electric guitars, electric mandolins take many forms. Most common is a carved-top eight-string instrument fitted with an electric pickup in similar fashion to many archtop semi-acoustic guitars. Solid body mandolins are common in 4-, 5-, and 8-string forms. Acoustic electric mandolins also exist in many forms.

A mandolin is a stringed musical instrument in the lute family and is generally plucked with a pick. It most commonly has four courses of doubled strings tuned in unison, thus giving a total of eight strings. A variety of string types are used, with steel strings being the most common and usually the least expensive. The courses are typically tuned in an interval of perfect fifths, with the same tuning as a violin. Also, like the violin, it is the soprano member of a family that includes the mandola, octave mandolin, mandocello and mandobass.
