“I’d be going through the rig but it wasn’t so much the GP-16 now. Before the amp, I’d be feeding from the H3000 Ultra Harmonizer in the control room, which is the Eventide studio rack effect that Alan was really big on. It made everything sound really - for want of a better word - epic! It had really great algorithms of reverbs and delays together and things that change within themselves after the notes finish. Live, we were still using the GP-16s until the end.”

This 2009 article about a contest where the prize was a chance to record in Gabriel's studio includes this photo of Peter in front of some of his gear. On the rack behind his right shoulder, an 80s-model grey-faced H3000 can be seen fourth from the top.

Lady Gaga uses the Eventide H3000 Ultra Harmonizer Effects Processor, as confirmed by her vocal producer/mixer, who stated: "I use around six outboard sends to physical plates and rooms that Henson has available, as well as an Eventide H3500 and an AMS RMX16 effects processor" (Mixonline, Lily Moayeri).

Hamilton used this processor in the late 90's.

"I used those with a variety of rack effects like the Yamaha SPX 90, and TC Electronic 2290, and Eventide H3000 in a stereo set up. A little later I also used a Roland GP-8. Slightly off topic, my Dad liked the sound of many of my presets on the GP-8 so I went to Guitar Center and bought him one. I copied all of my presets into it and he used it extensively on his 1988 tour. The clean sound that you hear him soloing with is him playing his blonde Performance Guitar through the GP-8."

Al Jourgensen frequently uses the Eventide H3000 Ultra Harmonizer Effects Processor both in live performances and on numerous tracks, as discussed on Gearslutz.

In this 2017 clip, Lanois is showing the camera around his studio. At the 1:27 mark, he points to his rack of older analog gear, in which sit not one, not two, but THREE H3000 units.

In this video, Sugizo's studio rack is shown to consist of two H3000's and a Roland Dimension D rack chorus.

Eventide H3000 is included in the list of Mark's studio gear.

Used on Jones' vocals for The Fall, as stated by producer Jacquire King in this February 1, 2010 Electronic Musician interview with Jones, Jacquire King and assistant engineer Brad Bivens.

She was into adding delay on her voice, trying not to just make it pretty with reverb. The delays were both analog and plug-in. I use Audio Ease Altiverb, SoundToys EchoBoy delay, some of the UA plug-ins—they have a nice EMT 140 emulation—and the Cooper Time Cube Delay. We used The Magic Shop’s Marshall Tape Eliminator AR-300, a tape slap simulator. And Norah had an old Ibanez analog delay. We used a Roland Chorus Echo and EMT 140 plate reverbs, too. Sometimes I will use an Eventide H3000 for harmonic delay effects, and as I get them going I will print them in Pro Tools with the transfer from analog.

In this April 15, 2009 Gearslutz forum reply, engineer Paul Arnold shares that, while working with Tupac during the recording of "Outlaw", he "also used a modified preset on the Eventide H3000 harmonizer called 'Magic Air' as the primary effect on his voice for 'space' in lieu of reverb, although certain mixes had plenty of reverb on his voice as well ('Only Fear of Death')."
