UltraSound Amplifiers was actually a shoot off of UJC Electronics. UJC Electronics was a company that was in the business of contract electronic assembly work (PCB Assembly) since 1985. The UltraSound Amplifier was the result of having an engineer, Greg Farres, on staff who spent twelve years in the music industry designing and producing amplifiers. It was Greg's desire to build and bring to market an amplifier that meets the musician's needs in the acoustic arena.
