Vintage 1970s MCI Univox Guitorgan Guitar-Organ Rare Factory Additions Mods READ Redburst Color

The guitar itself works however the Guitorgan Pedal and cable are missing so i have no way to test the functionality of the organ feature. More than likely it will work and if you have those components, you are in the money so to speak. However i can't guarantees that. The guitar is such good shape it probably works!  

It seems this version has an extra effects, drum machine or organ set added in the lower bougt. Thats not some ad on that a customer just slapped on there. It looks to be factory done. SURPISE gift to the winner of this vary rare and amazing guitar.

Check out this cool MCI Guitorgan Guitar Organ for sale! This certainly was an ambitious idea that came into fruition back the 1960s. Its a heavy guitar probably about 8-10 pounds. These are basically hi end teisco guitars outfitted with organ electronics. There are contacts on the frets that trigger the organ feature and you just play like normal!

Bob Murrell is credited with its invention and Musiconics International (MCI) of  claims to have introduced the Guitorgan. However, many others have created them starting with many models of the guitar. In any case, all have the basics in common: Convert a standard electric guitar into a Guitorgan through the addition of electronic organ components. The most critical part of making a Guitorgan is to separate each guitar fret into six segments, creating independent contact  for each string. The organ  are keyed when a string touches a specific segment, thus, making the ground connection necessary for the organ circuit to produce output.  circuitry determines the highest fret segment making contact on each string, and prevents simultaneous organ notes on the same string to activate; only the highest organ note played on a particular string will sound.

The organ section in a Guitorgan is a 6-note polyphonic circuit, which allows full guitar chords to be played. The guitar section always remains playable, but organ notes can be played alone or simultaneously with the guitar. The idea behind being a "Guitorganist" is to use the Guitorgan's expression pedal to creatively and accurately bring the organ in and out of the musical foreground while playing the guitar at the same time (and vice versa) as if there are actually two separate musicians playing.

Murrell worked on converting existing products from the late 1960s. In 1968, he had a significant run of instruments based on semi-hollow body guitars from Japan. The B-300 and M-340 are among the most common examples from this run. Also in existence are the M-300 and the B-35 models. The B-300 FSG (Frequency Synthesized Guitorgan) models, introduced in the early 70s along with the B-35, are based on a master oscillator circuit utilizing a special 12-note divider integrated circuit which is an improvement to the older 12 oscillator design, the advantage being that tuning the FSG organ circuit only requires adjustment of the master oscillator frequency rather than adjustment of each of the 12 oscillator frequencies on the older models. Note that FSG pedals cannot be used with non-FSG Guitorgans and vice versa, since the two versions run on a different DC voltage. The multi-pin cable that goes between an FSG pedal and an FSG Guitorgan was labeled with RED ends at MCI for a safety reminder.
