Rickenbacker 325

The Rickenbacker 325 is an electric guitar used by John Lennon during the late 50's to the mid 60's.

Overview
The  Rickenbacker 325 was the first of the Capri series of hollow body guitars released in 1958 by  Rickenbacker. It was designed by Roger Rossmeisl, a guitar craftsman from a family of German instrument makers. Production models were 20-3/4" short scale, dot fretboard inlays, and a small (12-3/4" wide) body. The body is unbound, semi-hollow, with 2'oclock angled soundhole (although re-issues lack a sound hole due to the Lennon connection), and boasts the "crescent moon"-style cutaways. This series is currently available only in "C" reissue form. These instruments gained prominence due to  John Lennon's use of a 325 during the early years of  The Beatles. John Lennon's 1958 model was among the very first batch made and has the pre-production feature of a solid top, i.e., no soundhole. All subsequent production short-scale 300-series Rickenbackers (310, 315, 320, 325) had soundholes until the late 1970s. (from Wikipedia)
