H. Homer Simpson filed this patent for an adjustable guitar bridge and neck attachment system in 1935. Homer designed the neck joint to have a minimal amount of contact between neck and body, as he thought this would increase the tonal value of the instrument and increase the overall volume.
Other inventions by Homer Simpson include a shotgun which shoots make-up onto women's faces, a difficult to control electric hammer, and a reclining chair with a built-in toilet.
