Anything you put through that box sounds cool and huge just by passing through the circuitry, which is a mark of good quality. I've had many hardware delay boxes, the H910 is special, I am totally in love with the H910, it is the sound of the late '70s David Bowie, the Cars, TV commercials etc. Designed by engineer Tony Agnello as a tool for pitch shifting, delay and feedback regeneration, it originally sold for 1,600, which is about 7,500 by today’s standards.

So I think spending 300 dollars for a plugin version might actually not a bad deal, if it sounds very close to the hardware and one is looking for that sound. H910 Harmonizer In 1975, Eventide released the world’s first commercially available digital pitch-shifting unit, the H910 Harmonizer. So I got a clean working unit for 700 bucks, but of course with the risk that the chips, now almost impossible to find, can go down at any time since these units are forty years old. I just had it completely refurbished (all the electrolytic capacitors replaced, all the chips disassembled and all components cleaned out etc.) and that cost $504.

I recently bought an original hardware H910 for 200 bucks 'as is, untested', and it miraculously worked, but it was noisy.

The software version is soooo expensive I could never consider using it.I have to give fellow GSers a caveat here. The original hardware units are usually cheap.
