"The Guitorgan started out in life as a Univox "Effie", a Gibson ES-335 copy. They were bought in quantity by Musiconics International out of Waco, Texas in 1969 and outfitted with organ parts. Each fret has six segments and when the string makes contact with the fret, the corresponding note sounds. It can be played as guitar, organ or both. It is believed that only about 3000 guitorgans were made. Bob Murrell is credited with its invention and Musiconics International (MCI) of Waco, Texas claims to have introduced the world to the Guitorgan.
