particularly in the US. The Jaguar was also sold in DIY kit form, allowing musicians to save money by finishing certain aspects of the assembly on their own. The Continental quickly became popular as it was advertised as part of the British Invasion of the mid-1960s, particularly after being endorsed by the Beatles. In order to increase supply, a licensing deal was signed between Jennings and the Thomas Organ Company in the US in 1966. Later that year, production for the US market was moved to EME in Italy for economic reasons; Thomas held a 30% stake in the EME factory, with Jennings and Royston holding 22%. The Italian Continentals used cheaper plastic keys glued to metal shafts, that were easier to break. There were also some minor cosmetic differences compared to older models, including a different vinyl covering, colours on the drawbar tips and construction of the stand. By 1969, the price of the Continental had dropped to $599 ($ as of ). In 1966, Vox produced the Guitar Organ, which put the internals of a Vox Continental in a Vox Phantom guitar body, and used a series of contacts along the frets so that a note would sound when a string was depressed onto a fret. John Lennon was given a sample instrument in the hope he would promote it, but it was never recorded and the instrument never entered full production. In 1967, Thomas manufactured the Voxmobile as a promotional instrument, designed by custom car designer George Barris. It combined a dual-manual Vox Continental with two oversized Vox basses, which were mounted onto a 289 cc Ford Cobra engine. The Continental Baroque was introduced in 1968, which combined the usual Continental manual with a multi-timbral one similar to that on other Thomas organs, and included a built-in amplifier. It sold for $1,598 ($ as of ), significantly more than the Super Continental. The additional sounds included banjo, harpsichord and celeste. It was considered unreliable and expensive, and did not sell well. Jennings struggled to retain control of Vox, and chief designer Dick Denney was fired on 19 September 1967, with employees loyal to him leaving shortly afterwards. Royston filed for bankruptcy two years later. The company was bought by Corinthian Securities who attempted to reintroduce a range of Vox Continentals, with the price of the Super Continental reduced from $999 ($ as of ) to $265 ($
