Used on Lamar's vocals for "All the Stars" as stated by producer Matt Schaeffer in this May 2018 Sound on Sound interview.

Kendrick Lamar’s vocal audio tracks, named after his teenage stage name K.Dot, consist of his first verse rap track, ‘VS 1 LD’, and 10 tracks for three moments in the track where he sings the pre-hook in a robotic voice. The verse rap track only has the AIR Flanger on it, and is sent to the ‘Dot VS LD’ aux track, which has eight inserts and five sends. Nine of the 10 pre-hook tracks have Auto?Tune, while the top four have a number of plug-ins on the inserts, including the EQ3 seven-band, Waves RVox, UAD Galaxy Tape Echo, SoundToys Little AlterBoy, SoundToys MicroShift and Valhalla Vintage Verb. These four are sent to a ‘Hook Ref’ aux track higher up in the session with another four plug-ins on the inserts and five sends. The other six are backing vocals to the four other pre-hook tracks and have no other plug-ins, other than a Trim, and are sent to a ‘Hook Background’ aux, just below them, which itself also is sent to the ‘Hoof Ref’ track. It’s a pretty complicated vocal signal chain, as Schaeffer admits.

“The ‘Dot VS LD’ aux indeed has a lot of stuff on it! I did most of the processing on that bus. On the inserts there are the SSL E-Channel, Waves RComp, Waves Q10 EQ, Waves DeEsser, UAD LA2A, UAD Pultec EQP1A, SoundToys Decapitator and Pro?Q2. The SSL channel strip, Q10 and RCompressor remain from the tracking, and maybe the DeEsser as well, but I most likely messed with the settings more during mixing. The Q10 has a high-pass at 50Hz and I notched out a frequency that was bothering me around 8.5kHz with the Q2. I added the other plug-ins during mixing, and they all add something a bit different. I’m boosting 100Hz and 16kHz with the EQP1A. As I said, I like using several EQs on one thing.

“The sends go to a ‘FlangeVerb’ track, on which I put the RVerb and the UAD MXR Flanger, then the ‘Huge Verb’ with the [Audio Ease] Altiverb and EQ3, ‘Hook Valhalla’ with the Vintage Verb, and the SoundToys EchoBoy, the ‘EMT250’ aux with the UAD EMT250, Valhalla Plate and MicroShift, and then finally a send to the ‘Dot VS Delay’ track, with the EchoBoy, set to quarter note, the Reel Tape Flanger and the RCompressor. The EchoBoy is the main delay you can hear in the verse. The EMT250 is not set to a reverb, but to a phaser effect, which gives a cool stereo effect. The Valhalla adds a bit of reverb here, though it’s set to -12, so it only gives a tiny bit of ambience, and the MicroShift makes the whole thing a little wider. It probably still sounded a bit dry, which is why I sent the track to the ‘Huge Verb’ aux with the Altiverb, again taking out low end with the EQ3."

"In terms of in-the-box effects, Arnalds is a great lover of UAD plug-ins, particularly the EMT 250 reverb and the Moog Multimode Filter. "I do a lot of side-chain filtering,” he says. "I might have a drum beat and send it out to an external bus as well with a filter and distortion and just layer that on top of the drum beat to give it a little bit more character and life. I like the Sound Toys Decapitator for distortion.”"

Used extensively on The Fall, as stated by producer Jacquire King in this Universal Audio interview.

And the EMT 250 is amazing. That's one of my favorite digital reverbs. It’s all over Norah's record, on all of the songs, I used the EMT 250 reverb plug.

Wavve's Nathan Williams shows his home studio, utilizing UA's EMT 250 reverb plugin. Most likely connected to his Spirit Club release, which includes ethereal reverb throughout.

Michael says he uses the UAD EMT 250 plugin in this interview

"I use lots of UAD stuff all the time. I love their verbs 140 + 250. I love their Studer, Ampex and Culture Vulture. Love the Silver compressor and Fatso"

In this Article, Bob Rock says

" I got an original EMT 250 and when the plug-in came out, I wanted to throw it across the room. The EMT 250 UA plug-in has no-hiss, it doesn’t break down."
