"Electric guitar wise, I like to use the Royer 121 in combination with a 57."

In a post from the official La Mesnie Herlequin Facebook page, Famine shares some of the gear used to record the latest Peste Noire album.

“On guitars, we had a selection of Royer 121s, Sony C37a’s, and I own a bunch of old ’60s Shure SM56s. Each amp would be double-miked with a condenser or dynamic, and a ribbon mic, and there were almost always two amps going at once,”

In an interview on Bobby Owsinski's Music Production Blog titled "Thank You, Ed Cherney - Part 2," it is confirmed that Ed Cherney used the Royer R-121 to record guitar amps.

I’ve been liking those and the musicians I’ve been working with have been liking them too. It’s pretty much just put the fader up and they capture what’s going on with the amp. They’ve got a very sweet character.

In this photo, Plati shared a bit of his studio rig. One of the items visible in this photo is the Royer R-121.

In the YouTube video titled "ニラジ・カジャンチ「プロのバンド・レコーディング全公開」前編" by SoundRecordingJP, Neeraj Khajanchi is shown using the Royer R-121 ribbon microphone. This microphone features a bidirectional pattern, a 2.5-micron aluminum ribbon element, and operates with a rare earth neodymium magnet. It offers a frequency response of 30-15kHz ±3dB, sensitivity of -50dB (1V/pa ±1dB), and an output impedance of 300Ω. The R-121 is equipped with an XLR3-pin male connector and can handle a maximum sound pressure of >135dB SPL. It comes with a dedicated wooden case for storage and protection.

At 42:35 in the video "Cozy LA HOME STUDIO Setup | DAVID PETERS 2026 Studio Tour" on YouTube, David Peters mentions and shows that he has a Royer R-121 ribbon microphone as part of his studio setup.

In this Instagram post, Jack Ruch says he uses a Royer 121 and shows it micing up his Fender Princeton Reverb. He says:

I finally upgraded my recording rig to the tried and true combo of a sm57 and a royer 121 through some nice api’s. I didn’t think it would make that big of a difference but it’s huge. Better late than never.

In the attached gear list from Christopher's website, under the software & hardware section, he cites his use of the "Royer 121".

Used on A Thousand Kisses Deep, as stated by recording engineer Joe Chicarelli in this December 1, 2003 Electronic Musician interview.

What mic were you using on trumpet?

Mostly a Royer 121, which you wouldn't expect to work in that situation because it's bidirectional. You'd think there would be a lot of bleed into the back of the mic. I tried it because I've used Royers on trumpets before and they sound nice and warm. On some songs, Chris thought the Royer was a little too dark, so we ended up using a Neumann U 67. But overall, I liked the Royer, especially for muted trumpet, which can sometimes get a little nasty in the midrange. We also used a Sony C37A for some songs; I remembered it was Herb Alpert's favorite trumpet mic!

Guitarist Edwin Marshal Syarif uses the Royer R-121 microphone for miking his cabinet during recording sessions, as evidenced by an Instagram post from @smosyu_music, which includes a detailed image of his setup.

In an Instagram story, the Royer R-121 microphone is visible in Michał Wasyl's studio, confirming its use by the artist. The story is captioned "w domu = @okolitza.studio".
