David Gilmour used the TC Electronic D-Two Delay during the 2015 recording sessions for his album "Rattle That Lock," as confirmed by Bjorn on Gilmourish.

Dimebag Darrell is known to use the TC Electronic D-Two effects processor, as detailed in the "Gearheads" section on Funksheet.

You can see in this picture two TC Electronic D-Two Delay in his rack.

This TC Electronic D2 Delay is used by Carlos Santana as his guitar tech recalls in the source.

According to TC Electronics website Robert Trujillo uses the D-Two Delay

TC Electronic D-Two Multi-Tap Rhythm Delay is based on the TC 2290. The D-Two can provide up to 10 seconds of delay, features 24-bit A/D-D/A conversion and 24-bit internal processing, comes with 50 factory presets and 100 user, and provides S/PDIF digital I/O at 44.1kHz and 48kHz. 6 unique direct-access features include Spatial (provides extra-wide delay at a single keystroke), Ping-Pong (pick any 5 patterns and set the relationship between panning speed and delay tempo), Reverse (reverse delay with the flick of a key), Dynamic (sets the release time and threshold to let the input signal control level of delay), Chorus (hit a single key to instantly add chorus or flange to your delay), and Filter (increases filtering as repeats decay). With the D-Two you are able to tap actual rhythm patterns consisting of up to 10 taps directly into the unit.

On the below picture you can see the rack of delays as used on The Wall tour in 2012. The rack includes Samson PowerBrite PB10 power conditioner and Korg DTR-2000 tuner.

Used for Albarn’s vocals on the Escape to Plastic Beach Tour, as stated by Albarn’s longtime FOH engineer Matt Butcher in this July 15, 2019 article by Entec Sound and Light.

“There are quite a few echo and delay cues, especially on Damon’s voice. I have an outboard rack with a TC D2 and a couple of Lexicon PCM81s in it, plus I’m using some of the internal effects for reverbs and delay for snare drums.

“When I was using a Midas Heritage on the first shows we did, I’d mess around with the tone generator and echo, along with guitar pedals to get some weird lo-fi effects. It was all very analogue and suited what we were doing and I’ve tried it with the D5, but I don’t really have as much time to play with these days!”

Summers also incorporated Marshall amps and a Roland guitar synthesizer into his rig. Of course, times have changed and so has Summers’ gear. For the ’07/’08 Police reunion tour, he used an elaborate two-piece Bob Bradshaw switching system, the right wing of which includes three Boss FV-500H Volume/Expression pedals, one used to control a rack-mounted Lexicon PCM 70 and two for an Eventide Eclipse, a Moogerfooger Analog Delay, and a Boss Loop Station and Chromatic Tuner. The left wing houses the main Bradshaw switching unit, plus another FV-500H and a Dunlop Cry Baby wah. Summers’ off-stage rack also contains his main Custom Audio OD100 amp and a Carvin DCM150 used to power stereo effects (each amp feeds two Mesa/Boogie Rectifier 2x12 speaker cabs), plus additional signal processors, including a T.C. Electronic TC1210 Spatial Expander/Stereo Chorus/Flanger, Bob Bradshaw V-Comp Tube Compressor, D-Two Multi-tap Rhythm Delay…

In this Sound On Sound interview, precisely on the "Jumble Sale Studio" section, a bunch of Jenkinson's gear is mentioned. Among them, the TC Electronics D-Two Delay. The item can also be seen in the photo gallery of the interview, along with other pieces in a rack (from top to bottom, TC Electronics D-Two Delay, DBX 1066, Drawmer LX-20 and the Eventide Orville). It is the 8th photo, here's a quick link to it: http://dt7v1i9vyp3mf.cloudfront.net/styles/news_large/s3/imagelibrary/S/Sq_09.jpg?3CE8TrbIbKGqUfDboUWA_6We1exoFnHv=&itok=6tgbEa6N

From the interview: "It's a ragtag collection of stuff, and there's no discernible overall 'vintage' rationale behind the collection as a whole. The most significant pieces are a Roland TR909, TB303, SH101, V?Synth XT and V?Bass 99, Neve 1073 mic pre, AKG BX15 spring reverb, TC Electronics D2 delay, DBX 1066, a self?made mechanical reverb, Tom Jenkinson's custom?made spring reverb: "The reverb uses four pairs of Accutronics type 1, 4, 8 and 9 springs. The stereo input stages incorporate a soft-clip circuit, high shelving EQ and spring selectors that send the input to a given pair of springs. There are four output stages to which the springs can be assigned. Each output stage has signal invert, volume and pan controls. The springs can be used in parallel or series, where one spring signal is fed into another. The circuit grounding uses star topology. It was used extensively on the album Hello Everything, in conjunction with my AKG BX15 and BX20 reverbs. It is clearly audible at the starts of 'Bubble Life', 'Circlewave' and 'Plotinus'.” Tom Jenkinson's custom?made spring reverb: "The reverb uses four pairs of Accutronics type 1, 4, 8 and 9 springs.

A huge amount of gear has also been and gone, like the Yamaha VSS80 8?bit toy keyboard sampler shown in some late '90s television footage of Jenkinson."

From an interview with the Prodigy's chief live sound engineer: "The [Roland] Dimension D is used to make the guitar big, because we've only got one guitarist and we try to make everything bigger than everything else. I've also got a [Yamaha] Rev 7 and a Rev 5. I've got them Y?split together because they've got a habit of stopping working, so one of them is usually working at any one time. They're both drum reverbs, I just run them both off the snare. Then I've got a guitar reverb, an SPX990, and a [TC Electronic] M2000 on vocals, which does harmoniser on some songs and reverbs on others. Then I've got a TC D•Two for all my more traditional delays.”
