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.

“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.”

"These are really cool analog choruses because plugin choruses just don't make it for me," says Steve Vai about the TC Electronic 1210 Spatial Expander Stereo & Chorus/Flanger which he uses in his studio rig.

In the comments, Aphex Twin wrote: "but i used things like the super smooth tc electronic 1210 for processing and akg spring verbs, big mixing desk etc".

In this YouTube video (3:56) from TC Electronic's channel, we can see John Petrucci's rack during the Black Clouds & Silver Linings tour.

At 7:54 in this "Rig Rundown" with Premier Guitar, Rush's Alex Lifeson's tech Scott Appleton shows us a TC Electronic 1210.

"... Los elementos centrales de su pequeño y simple set son el genial 2290 que la TC Electronics fabrica, la conocida reverb Ibanez SDR 1000, otro TC, el 1210 Spatial Xpander (Chorus y flanger) y el práctico GP8 de Roland, una especie de pedalera de rack con posibilidades de cualquier combinación entre compresor, over drive, chorus, flanger, etc. Complementa este modelo de verano un compresor dBX 163 X. Todo, pero todo, recae en un Mixer Yamaha de 8 canales, stereo (MV802). Ahora, es la responsabilidad del Hush IIC (stereo noise reduction) que la señal llegue al borde del abismo (un ecualizador gráfico de 31 bandas, stereo) sin ruidos ni molestias."

In this Guitar Player article, it lists the effects that Andy Summers uses on "Can't Stand Losing You." It reads, "Solo: Red Witch Empress Chorus + Eventide Eclipse + PCM 70 + T.C. Electronic TC1210 Spatial Expander/Stereo Chorus/Flanger"

In the Premier Guitar video "Rig Rundown - Def Leppard's Phil Collen," at 11:23, Phil Collins discusses his TC Electronic 1210 Spatial Expander Stereo & Chorus/Flanger, highlighting its place in his Marshall mount-rack setup.

"The electrics are sent to a Framptone amp switcher, which splits the signal off to four different paths. One route goes to a MESA/Boogie amp switcher that selects between a MESA/Boogie Mark IV rackmounted head powering a Hammond 147 Leslie (modified), or a MESA/Boogie Rectifier preamp. The preamp sends its signal to a pair of Digital Music dual stereo line mixers, which blend in the effects: a TC Electronic 2290 delay, TC Electronic 1210 chorus, Eventide Eclipse, dbx 1066 compressor, Ernie Ball volume pedal, Mu-Tron octaver, Foxx Tone distortion, Ampeg overdrive, and Korg DL8000 delay."

At 26:09, Larry talks about the TC Chorus, "...The TC chorus which sounds great because we're running stereo on stage for me so I really get the warmth of it not the mono backline kind of sound."

In this video, Phil Collen shows his rack rig which consists of the TC Electronic 1210 chorus unit.
