As demand for Vox guitars grew, particularly in the United States, a new enterprise between JMI, Eko and the Thomas Organ Company (the US distributors) was established - this was named EME, and like Eko was based in Recanati in Italy. EME guitars were widely fitted with electronic effects, and controls were labelled as such: distortion (dist), repeat percussion (repeat), treble/bass boost (tr-b boost), aswell as the standard volume and tone controls. The knobs were somewhat similar to the bell knobs used by Gibson in the 1950s and 60s, with a silver coloured metallic insert, and numbered 1-10.
These controls were fitted to all guitars built in Italy from early/mid 1967; guitars for the British market still had either the plastic or chrome JMI knobs that had been used over the previous years. Models include: the Vox Thunderjet, Delta, Invader, Apollo, Bossman, Cheetah, Ultrasonic, Star Stream, Grand Prix, Saturn, Aristocrat and Viper guitars, plus the Hawk, Delta, Sidewinder, Astro, Constellation, Saturn, Skybolt, Spyder and Stinger basses.
