Electric guitars were originally designed by an assortment of luthiers, electronics enthusiasts, and instrument manufacturers, in varying combinations. Some of the earliest electric guitars, then essentially adapted hollow bodied acoustic instruments, used tungsten pickups and were manufactured in the 1930s by Rickenbacker. The first recording of an electric guitar was by jazz guitarist Eddie Durham in 1937. Durham introduced the instrument to a young Charlie Christian, who made the instrument famous in his all-too-brief life and is generally known as the first electric guitarist and a major influence on jazz guitarists for decades thereafter.

The version of the instrument that is most well known today is the [solid body] electric guitar, a guitar made of solid wood, without resonating airspaces within it.

At least one company, Audiovox, built and may have offered an electric solid-body as early as the mid-1930s. Rickenbacher, later spelled RickenbackerRickenbocker) offered a solid Bakelite electric guitar, nicknamed "The Frying Pan", beginning in 1935, which reportedly sounded quite modern and aggressive when tested by vintage guitar researcher John Teagle.

Another early solid body electric guitar was designed and built by musician and inventor Les Paul in the early 1940s, working after hours in the Gibson Guitar factory. His "log" guitar (so called because it consisted of a simple 4x4 wood post with a neck attached to it and homemade pickups and hardware, with two detachable Swedish hollow body halves attached to the sides for appearance only) was patented and is often considered to be the first of its kind, although it shares nothing in design or hardware with the solid body "Les Paul" model sold by Gibson.
