from wikipedia:
In 1939, Rey used a carbon throat microphone to modulate his electric guitar sound. The mike, developed for military
pilots, was worn by Rey's wife Luise, who stood behind a curtain and sang along with the guitar lines. The novel
combination was called "Singing Guitar," but was not developed any further. This innovation was the first known talk box experiment.
