Electric mandolin 4-string version. A related instrument, the Bahian guitar, was developed in Brazil beginning in the 1940s. Bahian guitars typically have a solid body and 4 or 5 single-course strings tuned in fifths, but are considered to be electric versions of the cavaquinho rather than the mandolin. Both four string single course and eight string double course solid body mandolins have been produced by several makers, as well as five string single course models. From 1956 to 1976, Fender produced a four string version which they simply called the "Fender Electric Mandolin". Its body shape was based on a smaller version
Mandolin is the Roman style mandolin, which has influenced it. The Roman mandolin had a fingerboard that was more curved and narrow. The fingerboard was lengthened over the sound hole for the E strings, the high pitched strings. The shape of the back of the neck was different, less rounded with an edge, the bridge was curved making the G strings higher. The Roman mandolin had mechanical tuning gears before the Neapolitan.

Other modern manufacturers include Lorenzo Lippi (Milan), Hendrik van den Broek (Netherlands), Brian Dean (Canada), Salvatore Masiello and
