The Rickenbacker 12 string 340 is part of Rickenbacker's 300 series of guitars, the series for which Rickenbacker is perhaps best known. Also offered as a six string version (Model 330 respectively). During the Rose Morris Rickenbacker export to the UK, this model was available as the model 1997, and the 340 was called the 1998. Rather than featuring the standard Rickenbacker slash-shaped soundhole, both guitars featured an f-shaped violin soundhole, which made these guitars instant collector's items.
