An octave twelve is a type of 12-string guitar fitted with a short-scale neck {{convert|15.5|in|cm}} and a small solid body. It is tuned one octave higher than a standard guitar, giving it the tonal range of a mandolin and enabling a guitarist to emulate the sound of a mandolin sound without learning new fingering patterns required for actual mandolins. The effect is similar to that of applying a capo to a standard 12-string guitar at its twelfth fret.{{cite web|title=Music Skanner - How many strings?|url=https://www.musicskanner.com/best-electric-guitars-2016-epic-guide/|accessdate=24 March 2017|archiveurl=https://web.archive.org/web/20160816203650/http://www.musicskanner.com/best-electric-guitars-2016-epic-guide/|archivedate=2016-08-16}}{{failed verification|date=October 2021}} However, unlike a standard 12-string guitar, the courses of strings are tuned in unison rather than in octaves.{{citation needed|date=March 2017}}

The octave twelve was invented by engineers at Vox, which sold the octave twelve as the mando-guitar from 1964 to 1968. Notable users of the mando-guitar included Brian Jones of the Rolling Stones. Most modern octave twelves are modelled after the distinctive body shape of the Vox mando-guitar. It was also used on the introduction of the Beach Boys' "Wouldn't It Be Nice", from "Pet Sounds".{{citation needed|date=March 2017}}
