In a video titled "Tribute to the Legendary Mick Ronson Part 1" by Guitar Hangar, the Roland RE-501 Chorus Echo is identified among Mick Ronson's equipment.

In a 2018 Instagram post, Justin Meldal-Johnsen is seen in his studio with the Roland RE-501 Chorus Echo, highlighting its role in his setup.

"Removed while two guys recovered from alcoholic over enthusiasm. Thank you so much guys, that was really helpful :-/ Space echo RE-501, £900 plus £20 shipping. From my eBay listing- "Good condition. Japanese/US power (needs transformer). This is ex Verve circa Forth. Since, with my early work with the Verve, and our T-shirts, featuring my old 201, I'm one of the folks who are responsible for the escalation of the prices of these machines, and also since I've had not one but two Space Echoes stolen, I'm unfortunately joining the trend of Space Echo exploitation."

On top of the rack on the right of the desk, there are two Chorus Echos.

Used for the lead vocals on "Rolling in the Deep", as stated by mix engineer Tom Elmhirst in this September 2011 Sound on Sound interview.

Below that are the vocals, starting with the lead vocal ['LdVb'], which subs the verse, bridge and chorus tracks below, while 'LVSE' is a Roland RE501 Space Echo track that Paul had recorded. Below are the backing vocals. [...] There's also Paul's Roland Space Echo track, which I used throughout, and which was the only lead vocal effect in the first chorus.

As seen in John's photo from his website.

At the 0:08 mark, you can see a Chorus Echo with a Mackie mixer on top.

Used on Jones' vocals for The Fall, as stated by producer Jacquire King in this February 1, 2010 Electronic Musician interview with Jones, King and assistant engineer Brad Bivens.

She was into adding delay on her voice, trying not to just make it pretty with reverb. The delays were both analog and plug-in. I use Audio Ease Altiverb, SoundToys EchoBoy delay, some of the UA plug-ins—they have a nice EMT 140 emulation—and the Cooper Time Cube Delay. We used The Magic Shop’s Marshall Tape Eliminator AR-300, a tape slap simulator. And Norah had an old Ibanez analog delay. We used a Roland Chorus Echo and EMT 140 plate reverbs, too. Sometimes I will use an Eventide H3000 for harmonic delay effects, and as I get them going I will print them in Pro Tools with the transfer from analog.

An RE-501 can be seen in the far right of this photo of King's LBT studio from this June 28, 2018 Mix Online interview.

"Lohner's home studio is centered around a Pro Tools Mix system running on a Mac G4/400MHz. Some of his outboard selections include an Avalon Vt-737sp preamp, an Avalon U5 preamp, a Tech 21 SansAmp, a Roland RE-501 Chorus Echo and a Clavia Nord Lead synth."

As seen in many images as Pauls primary delay unit. "Also, notice the Roland RE-501 Chorus Echo. This was a tape-echo machine introduced by Roland in the early 80s; sadly, it was also their last electro-mechanical effects processor.

Again, this unit came packed with; you’ve guessed it, chorus effect! If you think about that, it kind of seems very logical right know, because his guitar sound it’s filled with modulation that seems to primarily come from chorus. Also, it’s worth mentioning that the Roland RE-501 has 5 different delay modes. He’s probably using settings 4-6 (which allowed the user to have two different delay times at once) in order to create the dotted eighth repetitions in some songs." - Thatdelaypedal.com (MM)

Used for Funeral for Justice as stated by producer Mikey Coltun in this May 28, 2024 Guitar World interview.

What details can you share about Mdou’s amp setup?

“[Mixing engineer] Seth Manchester and I reamped Mdou’s guitar through a Soldano SLO-100 and a Traynor 4x12 cab. This amp is made for Mdou. Since Mdou doesn’t play with a lot of dynamics and it’s pretty much just hard fingerpicking on the bridge pickup, there tends to be a lot of bright sizzly highs and not enough clarity. The SLO just scoops all the unwanted high frequencies out. For mics, we used a Neumann U 77 and Coles 4038, like, 3ft to 5ft away going into API preamps.

“After reamping, I throw a Space Echo [RE-]201 on the left and right sides for a bigger sound. There were no Roland JC-120s on this record – however, on some songs like Oh France, I used a Roland Chorus Echo [RE-]501 for that chorus sound.

“The chorus on the 501 is a bit different than the JC-120 – it’s more similar to the Roland battery-powered Cube chorus, which is widely used throughout all of West Africa and one of Mdou’s favourite amps.”
