Eventide

Recording engineer Stephen Katz, inventor Richard Factor and patent attorney Orville Greene started Eventide in the basement of a New York recording studio in 1971, and within a few years had built the DDL 1745, the first rack-mountable digital delay line. The H910 Harmonizer followed in 1975 as the world's first commercially available digital pitch shifter, and the Harmonizer name has stuck to Eventide's flagship effects line ever since, running through the H3000, the H9 and, most recently, the H90. Eventide's studio processors ended up on a huge number of records long before the brand became a pedalboard fixture; the H9 in particular condensed decades of rack-unit history into a single stompbox. We cover its pedal and plugin updates as they land. Here's what we've written.
