Rickenbacker also released their first electric bass, the model 4000, in 1957.
Designed by Roger Rossmeisl, this bass laid the foundation for all Rickenbacker basses that followed it, and its influence can be clearly seen in the current 40 bass models.
There are a few copies similar to the 4004 Cheyenne.
I've published this page on this site because I do not like copies of Rickenbacker instruments and I don't like to see anyone get fooled into buying a fake that has a Rickenbacker truss rod cover on it or a missing truss rod cover. One with a missing truss rod cover might be real/ The bass model that has generally been copied is the 4001.
I’ll give a little Rickenbacker history, explain why their basses are important, and discuss the specs and value of your bass.
Adolf Rickenbacker, along with two other men, started a metal stamping shop in 1925 called the Rickenbacker Manufacturing Company.
In the early 1930s, Rickenbacker and National employees George Beauchamp and Paul Barth formed a new company, called Ro-Pat-In, to begin developing Beauchamp’s electric guitar design—a design that National was not interested in.Triangle inlays, bound body and neck, triangle inlays. In the late sixties the factory also made some basses with ebony fretboard. Without a doubt there are even a few 4001's with later serial number dates, which would been 'stragglers' through the production process or 'clear off the shelf' goods." "The string tension of a round wound string, especially a nearly pure iron string like those in the Roto Sound class, is almost 100 lbs. The 4001 neck was designed in 1956 for the only type of strings available then . The 4003 has a completely different truss rod design and can handle any type of string you prefer. Round wound strings took many of these instruments beyond their rated capability for string tension, resulting in various problems.The Rickenbacker Company was founded by Adolph Rickenbacker and George Beauchamp in 1931 in Los Angeles.It was initially called the Electro String Instrument Corporation.
