"He also uses a Lexicon PCM-70 to store the circular delay sounds you hear in songs like "Shine On" and "Time." Because it has a multi-tap function, it can pretty accurately duplicate the kind of echo Dave used to get from his old Binson echo unit. A t.c. electronic 2290 is his primary delay -- it's what he uses for most things." - Phil Taylor, David Gilmour's guitar tech.

As part of his 1988 Soldano/Cornish Guitar Routing System, Eric Clapton used the Furman PL-8 Power Conditioner and Light Module, a SAMSON UR-5D UHF wireless receiver, a SAMSON BR-3 VHF receiver, a Drawmer 1960 tube compressor, a YAMAHA SPX-90 multi-effect processor, a Dyno-My-Piano CS-5 Tri-Stereo Chorus, a TC Electronics 2290 dynamic digital delay, a DYNACORD CLS 222 Leslie simulator, a YAMAHA GEP 50 multi-effect processor, a Roland SDE-3000 digital delay as well as the TC1210 spatial expander with VHS/UHF aerial unit at rear.

Matt Bellamy's effects rig for the Absolution tour included the TC Electronic 2290 Dynamic Digital Delay.

“The The live amplification is a racked set up based around two Boogie Quad preamps, a Boogie 295 poweramp, and a tc 2290. The tc's effects loop takes in a Yamaha GEP50, Roland GP8 and Korg A3 guitar processors, an Eventide H300 Harmoniser and a tc spatial expander. Speakers are two Marshall 2x12" cabs loaded with EVs, and the whole set-up is doubled for live work in case of breakdowns.”

This Music Radar article from the "360" tour details The Edge's full setup, and notes that the 2290 runs through his two AC30s.

This is a picture of the rack John used for the 2002 World Tourbulence tour. Among the various units there are two TC Electronic 2290 delay units (third and forth from bottom to top). Confirmation of this being John's rack can be found in this diagram from Guitar Geek and at :15s in this video.

On this photo, you can see TC Electronic 2290 Dynamic Digital Delay in Dave's rack.

The 2290 is among many effects used by Robert per this archived version of an April 2000 edition of Guitar World magazine. Sound on Sound also lists this as part of The Cure's gear set up here.

SATCH'S BOOTY

WITH HIS band, Joe Satriani plays custom Ibanez guitars with DiMarzio pickups and D'Addario strings. His amplifiers are Marshalls, usually a pair of 100-watt heads driving two 4x12 cabinets. "The amps are run clean. I've got a compressor in-line but I don't really use it. I use an Ibanez digital reverb, some Ibanez digital delay, a Cry Baby, different distortion pedals and a Boss CE-1 chorus, the rack I have is really filled with a lot of back-up stuff: an extra chorus, a Randall amp/pre-amp that I can use if my pedals don't work, a t.c. electronic delay. It's really low-tech, inexpensive, cheap, simple."

With Jagger, Satriani plays a Strat: actually a hybrid of Fender, Tokai, DiMarzio and Ibanez parts with a 1954 Fender neck courtesy of Joe's guitar tech, Pierre de Beauport of New York City. His main amp's a Marshall, but there's a Roland JC-120 with a Boss delay tucked away for 'Midnight'. He also uses a t.c. 2290. "It's got all sorts of loops that allow you to program whole sections. So Pierre, who has a script, can just punch me in and out of these little patches so I can get louder or softer, or there'd be some delay. I wanted to keep the stage as clean as possible."

When he's writing, Satriani uses a four-track Tascam Porta-studio. "I've got some Rockman gear and an array of cheap pedals at home. That's about it. Plus a lot of basses, synthesizers, guitars and cassettes lying around."

During an interview with Tape Op in 2001, Kevin shields comments on the recording of "To Here Knows When" about how he used a TC unit that did "Delays and Dynamics" on the drums:

"and then there's programmed drums and they're put through this TC unit, I forget what it's called, but it does dynamics and delay and it's just adds this weird sort of feel to it."

This passage can be found in the 4th section of the said article, Issue 26.

Tc 2290 Delay on guitar.

It’s effectively dry signal, which comes from the cabinet, the cabinet hits the monitor system, and we have a TC 2290 for his delays, and then a Lexicon for two big old plate reverbs, one at 1,600 milliseconds, another at 3,200 milliseconds. So it’s a short-ish reverb and a lush reverb, and then just a couple of delays.
