According to the book ''Classic Keys'' (2019), [[Vox (musical equipment)#GuitarOrgan|Vox '''Guitar Organ''']] was developed at latest in 1965 and released in 1966 by the Jennings Musical Industries Ltd (JMI) in the UK.<ref name=LenhoffRobertson2019p170/> It was roughly based on their Continental organ voice boards.<ref name=LenhoffRobertson2019p170/> In 1965, its sample was given to [[The Beatles]], and [[Thomas Walter Jennings]], a founder of JMI/Vox, said "''We hope that with in a few months, they're going to be spreading it all over the world''" in a television interview. [[John Lennon]] liked it enough to keep it, but it was never used on the Beatles recording session.<ref name=LenhoffRobertson2019p170>{{harvnb|Lenhoff|Robertson|2019|p=[https://books.google.com/books?id=d4LCDwAAQBAJ&dq=VOX%20Guitar%20Organ&pg=PA170 170]}}: {{smaller|1="''Also in 1966, Vox introduced one of its most inventive and unique products, the Guitar Organ. It was a version of the Vox Phantom guitar that included the sound generating technology of the Continental organ. ...<!-- It could also be played as a standard guitar or with organ and guitar voice combination. It was powered by a remote power supply box that converted AC power into the various DC voltages required by the organ electronics. This was tethered to the Guitar Organ by a multi-conductor cable. --> The organ section had six tone generators, one for each of the guitar strings. Electronic contacts were built into each of the frets, and tones were produced when any of the guitar strings was depressed to touch a fret. ...<!-- A series of resistors positioned along the length of the neck determined the pitch of each note played. The Guitar Organ offered the player a choice of organ or flute tones, and percussion, sustain, and octave effects. Vox said it could produce full organ chords “using only normal guitar techniques.” Its US list price at introduction was $995, which included a case. --> / In 1965, a sample was given to The Beatles by Vox, and the company told reporters that John Lennon was practicing with it, and The Beatles' next album would feature it. “We hope that with in a few months, they're going to be spreading it all over the world,” Tom Jennings said in a television interview. But that didn't happen. Lennon liked it enough to keep it, but apparently not enough to ever use it on a Beatles recording session. ...<!-- / According to the book ''Beatles Gear'', it later fell into the hands of a Beatles roadie, whose widow eventually sold it at auction for £10,000. Many players found the guitar organ to be unreliable and hard to use, and the product died quickly. -->''"}}</ref>

According to the [[Billboard (magazine)|Billboard magazine]], similar instrument named '''GuitOrgan''' seems introduced circa August 1967 by Murrell Electronics in Waco, Texas.<ref name=Billboard1967August19p16>{{harvnb|Billboard|1967|p=[https://books.google.com/books?id=9ykEAAAAMBAJ&dq=VOX%20Guitorgan&pg=PA16 16]|loc='Guit-Organ' From Texas Company}}: {{smaller|1=''WACO, Tex. Murrell Electronics here has introduced new combo instrument concept that plays like a guitar, sounds like an organ, a guitar or a guitar and organ combined.. The firm calls the instrument a "GuitOrgan." / The firm, new to the instrument business, is expected to introduce a complete line of professional-quality guitars and amplifiers soon. All will be usable with the GuitOrgan tone generator. / The complete outfit consists of a guitar with electronically modified fret board, a solid state organ-tone generator with Baldwin components and a foot expression pedal. The tone generator has 10 tone-selector stop tabs.''}}
</ref> The invention of the GuitOrgan is credited to Bob Murrell and Musiconics International (MCI) of [[Waco, Texas]].<ref>{{cite magazine|url=https://books.google.com/books?id=NSgEAAAAMBAJ&q=%22Guitorgan%22+-wikipedia&pg=PA53|title=MusiConics' Portable Organ Puts Firm Into Mass Market|magazine=Billboard|pages=1, 53|date=March 14, 1970|accessdate=February 12, 2021}},</ref> 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.{{citation needed|date=February 2021}} The M-300 model was introduced at the 1970 [[NAMM Show|NAMM Convention]].<ref>{{cite magazine|url=https://books.google.com/books?id=dykEAAAAMBAJ&q=%22Guitorgan%22+-wikipedia&pg=PA10|title=NAMM Bullish on Rest of '70|magazine=Billboard|date=June 20, 1970|pages=1, 10|accessdate=February 12, 2021}}</ref>

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 using a 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. 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. Murrell continued to introduce upgrades to the Guitorgan design that included [[analog circuit|analog]] [[synthesizer]] interfaces and even [[MIDI]] in the mid-1980s.

In the mid-'70s, Godwin produced the rare Organ (Guitar) in two versions.  The flagship model had 19 switches and 13 knobs, while the lower model had 16 switches and 4 knobs.{{citation needed|date=February 2023}}
