The Rickenbacker 370 is very similar to the 360 series with the exception of having 3 vinatge pickups instead of two. The 370 is a semi-hollow body construction with trapeziod pearl fret markers and an "R" style tailpiece. The Rickenbacker 270 is equipped to be compatible with a "Ric-O-Sound" unit via an extra "stereo" output socket that allows the two pickups (or neck and middle pickup combined/bridge pickup, in the case of three pickup instruments) to be connected to different effects units or amplifiers. Rickenbacker has discontinued the 370 series, making it an extremely rare guitar.
