Editing Rickenbacker (section)

===Model B Electric===

In 1935, the company introduced several new models including the Model "B" Electric Spanish guitar, which is the first known solid-body electric guitar. Because the original aluminum Fry-Pans were susceptible to tuning problems from expansion of the metal under hot performing lights, they made many of the new models from cast [[Bakelite]], an early synthetic plastic used in [[bowling ball]]s.<ref name=Bacon/>

Rickenbacker continued to specialize in steel guitars well into the 1950s, but with the advent of [[rock and roll]], F.C. Hall, owner of Radio & Television Equipment Co. (Radio-Tel), purchased the Electro String Company from Adolph Rickenbacker in 1953. Hall overhauled the business and began focusing on standard electric and acoustic guitars rather than the steel guitars the company pioneered. In 1956, Rickenbacker introduced two instruments with the "[[neck-thru|neck through body]]" construction that became a standard feature of many of the company's products, including the Combo 400 guitar, the model 4000 bass, and, later, the 600 series. Neck Thru consists of a single wooden piece from the neck through the central body section.

In 1958, Hall introduced prototype called "capris" (the same name of Hall family's cat from the pronunciation of the French noun for whim).<ref>{{Cite web |url=https://www.premierguitar.com/articles/20913-vintage-vault-1964-rickenbacker-325 |title=Vintage Vault: 1964 Rickenbacker 325 |website=premierguitar.com |access-date=March 12, 2019}}.</ref>

In 1963, Rickenbacker developed an electric twelve-string guitar with an innovative [[headstock]] design that fit all twelve [[machine head]]s onto a standard-length headstock by mounting alternate pairs of machine heads at right-angles to each other.
