The Eventide H910 Harmonizer was first demonstrated to universally positive reactions at the AES show in late 1974. It was designed by Eventide's first engineer, Tony Agnello (who went on to become the president of Eventide's audio division). The pre-production prototype was a hand-wired box topped with a music keyboard controller. Jon Anderson of the band Yes was among those impressed, and he became a tester for the first prototype. The production H910 was released in 1975, offering pitch shifting (±1 octave), delay (up to 112.5 ms), feedback regeneration and other features in an easy-to-use box that sold for $1,600. The H910 was named after a Beatles tune (the model number refers to the "One After 909").
The first H910 customer was New York City's Channel 5, utilizing it to downward pitch shift I Love Lucy reruns that were sped up to create room to run more commercials. Speeding up the reruns had increased the pitch of the audio, and the H910 was able to shift that pitch back to where it originally had been. Frank Zappa added it to his guitar processing rig. Producer Tony Visconti used the H910 to create the snare sound on David Bowie's album Low (1977), as did Tony Platt on AC/DC's song "Back in Black" (1980). Another popular application was to use two H910s slightly detuned with a small delay. Notable users of this twin Harmonizer effect included Eddie Van Halen, who used it for his trademark guitar sound, and Tom Lord-Alge, who used it for the vocals on the hit Steve Winwood song, "Back in the High Life Again" (1986). Recognizing the popularity of this application, Eventide later recreated it as the "Dual 910" program in the H3000 UltraHarmonizer released in the late 1980s.
The H910 Harmonizer was recognized by the AES with a TECnology Hall of Fame award in 2007,[4] and on November 10, 1976, Eventide filed a trademark registration for "Harmonizer," and Eventide continues to maintain its rights to the Harmonizer trademark today.[5]
