Eventide H3000-SE (1990–)
Little formal documentation survives for the H3000-SE specifically. Eventide's own service literature and the period trade press give a clear enough picture. The H3000-SE - "Studio Enhanced" - was the top of the H3000 Ultra-Harmonizer line, above the H3000-S and H3000-B. Eventide's software-revision notes treat it as a distinct hardware build. The SE runs its own EPROM set: SEROM1 operating system, SEROM2 algorithms, SEROM3 factory presets, plus an optional SVAIROM and a self-test ROM. The SE's algorithm and preset ROMs are 1 M devices, where the S and B machines used 512 K. Version 2.16 is the operating-system revision named for the SE in that list.
Eventide's 1990 advertising pitched the SE as an improvement on the original H3000 Ultra-Harmonizer, "the most successful Harmonizer in Eventide's history." Mix (April 1990, p.95) and Studio Sound (July 1990, p.75) both ran that campaign. It highlighted a new Function Generator for programming autopanning, arpeggios, sweeping flangers and randomized vocal doublers, plus "Soft Functions" that let users customize the front panel. EQ (July 1990, p.75) reported that existing H3000-S units could be updated to SE performance through a $600 factory upgrade, and mentioned a true stereo sampling option. The surviving material doesn't spell out what the SE adds over the S in hardware terms, beyond the larger ROM set.
Used-market evidence from the trade classifieds puts an H3000-SE at roughly $2,300 - $2,400 in the early 1990s. That is about all the pricing record offers.
The H3000-SE is well attested as a real model in Eventide's own revision tables and in 1990 advertising. A dedicated owner's manual or full spec sheet hasn't surfaced in this archive.
