Visually similar to the Rickenbacker 360, the 360-12 was among the first electric twelve-string guitars ever produced. It also uses an innovative headstock design that incorporates both a slotted-style peghead and a solid peghead, thereby eliminating the need for the larger headstock normally associated with a twelve-string guitar. Another feature unique to Rickenbacker twelve-strings is the ordering of the strings. Most twelve-strings have the octave on the bass side of the matched strings; Rickenbacker reverses this convention. The 360/12 was given worldwide attention by George Harrison, who used it on many Beatles recordings, beginning with 1964's "A Hard Day's Night."
