According to the lot notes from Bonhams auction house website, Eric Clapton used the Ibanez HD1000 Harmonics/Delay, a DBX 160 compressor, a model SDE-3000 Roland delay, a Dyno-My-Piano Tri Stereo Chorus, a Boss CE-1 chorus, and a Boss HM-2 Heavy Metal pedal for his Bob Bradshaw rack system in the mid to late 1980s.

This effects processor was sold on Billy Corgan’s official Reverb.com shop.

In this guitar player interview from April 1986 Alex was asked,

What causes the Far Eastern tone in the opening of "Territories"?

That's just the Ibanez HD-1000 Harmonics/Delay set at an octave above with a little bit of modulation. The harmonics level is set at about 70%, the direct is set at the full 100%, and I was on the middle pickup on the black Strat. I used left-hand finger-pulls. After that, it switches to a much crisper tone, and to do that in concert, I just switch to the back pickup.

"Out of there I go into an Ibanez 1000 harmonizer, usually an octave up. They're nasty if you've used an AMS, but for £300 they do the job. If you wind up the feedback you get a lovely sort of organ tone out of the guitar."

ADRIAN BELEW'S EQUIPMENT

Adrian Belew says, "I'm using four guitars now. First are the two Twang-Bar Wonderbeast guitars with artwork by Mike Goetz. Each has a different tuning — one is normal, the other has the G tuned up to A so I can get different voicings and avoid pentatonic scales. Starting off at the headstock, they have bow-and-tuning heads, thereby eliminating the need for retaining bars which stop you from being able to play in the back of the head or bend strings at the nut. They have Seymour Duncan pickups, Kahler tremolo arms, and all the guts from the Roland synthesizer. The same is true of the third guitar I use, except that the artwork is by Laurie Anderson, and that it's tuned to the same tuning as my dobro, E-B-E-E-B-E, with heavier gauge strings, the low E being a .052 and the high E being a .012. Usually I use medium-light Gibson strings, with the high E being a .010 and the low E a .042 I use Fender medium picks. The fourth guitar is my battered 1967 Stratocaster from the David Bowie period, with a broken bass pickup [laughs] and it feeds back better than any other guitar I have.

"My two amps are Roland JC-120s — I've used one on everything from 1977 on. Right now, my floor situation looks something like this — I have the GR-700, the Roland SDE-3000 delay, an Ibanez harmonizer, a Big Muff fuzztone, a Foxtone fuzztone, the Electro-Harmonix echo-flanger — which makes the wonderful metallic insect sounds on Desire — the new Roland compressor — I always use lots of compression — a Roland pitch-shifter, and the Electro-Harmonix 16-second delay, which I've had converted to do backwards tape loops."

According to this scanned copy of the publication The Armoury Show, John is shown as using an "Ibanez HD1000" in his setup.

In the YouTube video "Analog Mixing & Jonathan Wilson's Home Studio" by Produce Like A Pro, Jonathan Wilson discusses his use of the Ibanez HD1000 Harmonics/Delay in his studio setup.

"I also have a Roland 31-band graphic equalizer, the SEQ 331, a T.C. Electronic 1140 parametric equalizer, and an Ibanez HD-1000 Harmonics/Delay on ‘The Family and the Fishing Net’ for doing sound effects an octave up. I have quite a long delay on it – about 310 milliseconds – with a lot of feedback.”

In the official music video for White Denim's song "Light On," a collage of numerous clips and shorts by James Petralli, at 1:40 we see part of the studio in the lower left corner and behind the drum tom we see different pieces of studio equipment, including the Ibanez HD1000 Harmonics/Delay, recognizable by its six colorful buttons and seven black knobs.

Absolutely everything in the studio goes direct into a patch-bay rather than the Soundtracs 16-8-16 mixer, even the Linn Drum. His effects range from a few Rebis modules, to a Ibanex HD1000 DDL, MXR Graphic Equaliser, and Electro Harmonix Instant Replay unit. There are also about five cheap and noisy effects pedals. Monitoring is via a pair of the ubiquitous Auratones whilst his latest purchase, a Sony PCM F1, has relegated his Revox B77 to the role of tape echo. The Sony is "a very neat little video machine. Betamax is much better than VHS because you can freeze frame upon frame which is great for me because I like working with pictures. It's brilliant for outdoor work too — it's lighter than a Uher and when you add a camera its a video!"
