The first Bass Guitar was invented by Paul Tutmarc in Seattle, Washington, USA in the early 1930's. It was known as the "Electric Bass Fiddle," and appeared in a catalog by Tutmarc's company, Audiovox, in 1935. Much smaller than the double bass, this bass was easier to carry. This bass was not fretted, however, and was not quite as popular as its descendant.
The "Electric Bass Fiddle" design was innovated greatly by Leo Fender, founder of what is now known as Fender Musical Instruments Corporation. Using a telecaster-body design, Fender came out with the "Precision Bass," a.k.a. "P-Bass" in 1951. It was fretted like a guitar, which allowed players greater ease in playing in tune (hence the name: "Precision Bass"). Not only was this model easier to carry than a double bass, but it was also much easier to play in tune. This model was extremely popular and was the first bass guitar as we know it today.
