Eventide's H3000 UltraHarmonizer series took its original 1975 H910 and (1982) H969 Harmonizer pitch shifters to new heights, offering the first processor with human-like, intelligent/diatonic pitch shifting. But it didn't stop there. Later incarnations of the H3000 ranged from the H3000B "broadcast" model (that even included helicopter sounds to simulate an in-air traffic report, even when the reporter was in an office) to the D/SE version with instrumental presets by guitarist Steve Vai and studio effects from top mix engineer Bob Clearmountain. And original H3000 users weren't left out of the fun, as Eventide offered ROM upgrades and a sampling board option to keep earlier units up to date. Although discontinued in 2000, the H3000 UltraHarmonizers are still in demand in music, studio and live applications.
