An electronic instrument that allowed the guitar player to play the organ and guitar. Essentially, it is an electric guitar with electronic organ components added. Each guitar fret is separated into 6 segments, creating independent contact switches for each string. The organ notes are keyed when a string touches a specific segment. An expression pedal is used to fade the organ sound in and out, while the guitar can be played at the same time.

The first guitarorgan was introduced by Musiconics International of Texas, but Vox quickly produced their own version known as the Guitar Organ.
