David Gilmour used a Roland SDE-3000 in his rack during his 2006 tour, as documented by Bjorn on Gilmourish. It was specifically utilized for the "Sound on Sound" effect.

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.

Mix engineer Tommaso Colliva on recording Drones : "Pedal–wise there was a lot going on, but there are a few pedals that get used a lot, like the ZVex Fuzz Factory, the ZVex Super Hard On, which gives a nice clean boost so it distorts the amplifier, the Super Duper, and the Machsonic Thrust Drive pedal, which is made by someone in Turkey, and which we used with the Ampeg head for a very scooped–out fuzz sound, the JHS Colour Box, which mimics the sound of the Neve 1073, and a Roland SDD 3000 pedal."

According to Premier Guitar, Eddie's set at the Bridgestone Arena in 2012 features a "pair of trusty Roland SDE-3000 delays".

For the 1988 David Lee Roth and 1990 Whitesnake world tours, Vai used this digital delay as part of his offstage effects rack.

Neil Young's ownership of a Roland SDE-3000 digital delay is documented in Julien's Auctions' December 17, 2017, "Neil Young Online Auction," listed as Lot #17 in the second group (#3198).

In this article from International Musician magazine (reproduced on Sting's official website), long-serving tech Danny Quatrochi explains that Sting has used an SDE-3000 as part of his live rig.

The digital delay unit is shown in the Star licks instructional video. Steve uses 2 units set at different speeds varying on the songs he plays.

Belew lists the SDE-3000 among his "floor situation" equipment in the December 1986, Downbeat interview "Adrian Belew: Twang Bar King" by Gene Santoro.

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."

In the effects rack lie the new Roland delays the SDE-1000 and SDE-3000. It transpires that these were quite a find for Gary and they now get put to great use on both voices and instruments.
