Guitorgan

From Wikipedia, the free encyclopedia

A Guitorgan is basically an electric guitar with electronic organ components added.

Bob Murrell is credited with its invention and Musiconics International (MCI) of Waco, Texas claims to have introduced the world to 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 switches for each string. The organ notes are keyed when a string touches a specific segment (only the highest fret-segment played on a particular string will sound), thus, making the ground connection necessary for the circuit to produce output. The organ section in a Guitorgan is a 6-note polyphonic circuit, which allows full guitar chords to be played. There is also a button on the Guitorgan's neck that allows the use of open chords. 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, were based on a master oscillator circuit with a digital note divider instead of the older 12 oscillator models. Note that FSG pedals CAN NOT 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. Bob continued to introduce upgrades to the Guitorgan design that included analog synthesizer interfaces and even midi in the mid 1980s.

Vox also produced their own version, known as the Guitar Organ, which was roughly based on their Vox Continential Voice Boards. This is an extremely rare item.

Godwin also produced the rare Organ Guitar with 19 switches and 13 knobs.

Some of the famous sounds produced by guitorgan can be heard in Teisco Del Rey's "The Many Moods of."

Bill Dillon is another practitioner of the Guitorgan. He has been featured on many Sarah McLachlan albums and appeared with the Counting Crows.

Woody Jackson's talents on the guitorgan can be heard on Orchestra Superstring's self titled album and many film soundtracks Ocean's Thirteen,Ocean's Twelve, Fun with Dick and Jane, The Devil Wears Prada to name a few. Also playing live show's with Money Mark and Eleni Mandell.
