paragraph_text: The origins of the solid body electric guitar are confusing. The first commercially available solid body electric Spanish guitar was produced by the Rickenbacker company in 1931. Les Paul, a guitarist, is often erroneously credited with inventing the first solid body, but Fender is often incorrectly credited as the first to commercially market a solid body electric guitar, which itself was based on a design by Merle Travis. Also it is reported that around the same time (1940) a solid body was created by Jamaican musician and inventor, Hedley Jones. In the 1940s, Les Paul created a guitar called the ``Log, ''which came`` from the 4'' by 4 ''solid block of pine which the guitarist had inserted between the sawed halves of the body that he'd just dismembered. He then carefully re-joined the neck to the pine log, using some metal brackets.'' He then put some pickups that he designed on it. He soon went to companies asking if they would buy his guitar. They turned him down. However, after the Fender Telecaster electric guitar became popular, the Gibson company contacted him and had him endorse a model named after him, The Les Paul guitar. It came out in 1952.

paragraph_text: In the 1930s, musician and inventor Paul Tutmarc from Seattle, Washington, who was manufacturing lap steel guitars, developed the first electric string bass in its modern form, a fretted instrument designed to be played horizontally. The 1935 sales catalog for Tutmarc's electronic musical instrument company, Audiovox, featured his ``Model 736 Bass Fiddle '', a four - stringed, solid - bodied, fretted electric bass instrument with a 30 ⁄ - inch (775 - millimetre) scale length. The adoption of a guitar's body shape made the instrument easier to hold and transport than any of the existing stringed bass instruments. The addition of frets enabled bassists to play in tune more easily than on fretless acoustic or electric upright basses. Around 100 of these instruments were made during this period.

paragraph_text: Mandolin awareness in the United States blossomed in the 1880s, as the instrument became part of a fad that continued into the mid-1920s. According to Clarence L. Partee, the first mandolin made in the United States was made in 1883 or 1884 by Joseph Bohmann, who was an established maker of violins in Chicago. Partee characterized the early instrument as being larger than the European instruments he was used to, with a "peculiar shape" and "crude construction," and said that the quality improved, until American instruments were "superior" to imported instruments. At the time, Partee was using an imported French-made mandolin.
