Used for the vocals and electric guitar on "Sex on Fire", as stated by Only by the Night producer Jacquire King in this December 2008 Sound on Sound interview. An image for the vocal settings can be found here.

• Vocals: Sound Toys Echoboy, Audio Ease Altiverb, Massenburg DesignWorks EQ, Neve 1099, Urei 1176, Dbx 902, Dolby A encoder, Teletronix LA3A

"I had a Sound Toys Echoboy delay and an Altiverb reverb, set to the EMT 140 plate, on the vocals. In fact, there are two or three delays and two or three reverbs in total, different amounts in different sections of the song. I had a Massenburg plug–in EQ on the vocal bus, and underneath it you can see my insert signal chain: Neve 1099 EQ/Urei Blue Stripe 1176/Dbx 902 de–esser. I pre-mix in my computer and things are coming out in stems, and going out into the desk and the Folcrom mixer for mixdown to stereo. The 1099/1176/902 were inserted in the analogue realm and daisy-chained. There's also a distant lead double in the chorus. I call that a performed effect. Instead of using a delay and modulation to get something in the background, you record a second performance in a different space and with a different microphone. You get something more deliberate and unique that way. Finally, once it came to summing, I also added some Dolby A to the vocals, which gives an excited high-frequency sound that I sent through an LA3A and blended back in."

(...) "I also used an Echoboy for delay on certain sections, like in the choruses. There was a little bit of bus compression on the guitars and a little bit of EQ, all very minor stuff, because I had already recorded what I wanted. The only radical EQ is on the Cooper Time Cube delay, which I described above, and which I applied to Caleb's guitar. I took out everything below 861Hz to get rid of the darker tone that was obscuring the source tone a bit. There's also a bit of Digirack delay on Caleb's guitar, to give it a bit more dimension by panning it to the other side than the track itself."

I'll bring in some delay. If not the Space Echo or the Memory Man, I'll go with software and use Soundtoy's Echoboy. Although Echoboy emulates a lot of hardware I have in the studio, I find myself using it more and more, simply because of how flexible it is. And it really nails the sounds—it's hands-down the best software delay out there.

In a YouTube short titled "Why FKJ Loves Soundtoys Plugins," FKJ mentions using the Soundtoys EchoBoy Analog Echo Processor.

EchoBoy is the first plugin on the sixth channel strip from the right in Firebeatz's track in their "In The Studio" video. (33:47)

Used for the electric guitar on "Sex on Fire", as stated by Only by the Night producer Jacquire King in this December 2008 Sound on Sound interview.

"We had five or six guitar amplifiers available for each guitar, and again, we picked the ones that were most appropriate for the song. Angelo and I would listen to the guitar parts and mix and match amplifiers. Sometimes we'd put reverb on one amp and a delay on another, or effect pedals on both. We had all kinds of combinations, although we kept it to two amplifiers per performance for each player. I'd put an SM57 in front of one amp and a U67 in front of the other. The guitars went through API mic pres, an API 550A EQ, and I also used some APSI parametric EQs. Occasionally I'd put an 1176 in the signal chain, but in general I don't use much compression on distorted electric guitars going to tape, because there's not a lot of dynamic range to them as it is. The synth–like reverb you can hear on the guitar was done at Blackbird on an Eventide DSP4000 and added during the transfer to Pro Tools.

"Using a guitar amp, I added a short slap delay on Matt's guitars. I also used an Echoboy for delay on certain sections, like in the choruses. There was a little bit of bus compression on the guitars and a little bit of EQ, all very minor stuff, because I had already recorded what I wanted. (...) The Altiverb on Matt's guitar is a very small room at Cello Studios, for a little bit more space."

Used for J. Cole's feature on 21 Savage's "A Lot", as mentioned by producer Maddmix in this March 2019 Sound on Sound article.

"The session was originally a 21 Savage track, and they later decided to add J Cole. His engineer sent me J Cole's vocal session with reverbs and delays already set, so I pretty much imported his vocal auxes, and just matched that to the mix that I had already going. However, the inserts are all mine, and similar to what I used on 21. There also are four Pro-Q2s here, plus two instances of the C6 multiband, and the Clariphonic EQ. The 'Slap' is a send to one of my aux effect tracks, just with a 30-millisecond EchoBoy delay, to widen the vocals a bit. I stripped all the other sends down, to match J Cole's vocals with a track that was more on the dry side, and actually disabled all the sends apart from the 'Slap' on the J Cole aux group track, 'Leads'. Finally, both '21 Leads' and 'Leads' go to the 'Lead All' [40] and parallel 'MadVoxComp' [41] tracks, and the latter has the Waves CLA-76 and L1, both for more presence and volume."

Used on the vocals for "Take Me to Church", as stated by mix engineer Rob Kirwan in this March 2015 Sound on Sound interview.

• Vocals: Bomb Factory 1176, Focusrite Red EQ, SoundToys Echo Boy, Line 6 Echo Farm, Knas Ekdahl Moisturizer, Waves Renaissance Compressor, Avid Trim & Audio Ease Altiverb.

“The two ‘tele’ voices at the top are backing vocals. I think they were ‘oohs’ and ‘aahs’ that came from the demo. They don’t sound like telephone voices at all, so I’m not sure why they’re called that. Instead they almost sound like church voices. Below are two aux tracks for those vocals, with Bomb Factory compression, Focusrite EQ and an Echo Boy delay. The backing vocals below that — ‘BV1–4’ — are the ones with the signature Leslie effect on them, and they again have some Focusrite EQ and Bomb Factory compression, and I gave them some Echo Farm slap delay to add depth to the reverb.

“The next tracks are the verse lead vocals from his Logic session, called ‘Male Creamy Lead Vocals’, on which I put some Renaissance compression and a Trim, and ‘Vox Verb’ is the Moisturizer track, plus two Trim plug–ins, one being +1dB and the other –0.5dB. I hate automating in Pro Tools, so I will often use the Trim to bypass it. Writing automation is a tedious task. Below this are the chorus vocals, called ‘New Vocal’, so we obviously recorded these again at my studio. In order to make them sound like the demo vocal I stuck them through the same chain and EQ’d them heavily. ‘Vox Plate’ is the Altiverb, and there’s a delay track below it which again has the Echo Farm, on a delay setting. Finally there are several more double–tracked chorus vocals, and they also have the Renaissance and Focusrite, and the Moisturizer and Echo Farm aux tracks below them.”

In a studio session in France for "Utopia," a screenshot reveals the use of the Soundtoys EchoBoy Analog Echo Processor on the right side of Travis Scott's screen. Despite the image being blurry, the distinct layout with the Soundtoys logo above the Saturation section, along with the visible "mode" knob and the labels for different modes and the "feel" knob, confirm the presence of EchoBoy.

In an interview with Resident Advisor, Jon Hopkins discusses using the Soundtoys EchoBoy Analog Echo Processor, highlighting its capability to create reverb-like sounds through its control over diffusion and delays.

"Antonoff’s favourite outboard reverb is the spring in his Roland Chorus Echo. Plug-in-wise, he tends to use the Waves Renaissance Reverb and Valhalla’s Plate, SoundToys’ EchoBoy for delay and, for more extreme effects, SoundToys’ FilterFreak, PanMan and Crystallizer granular delay."

"Plug in wise, SoundToys Echoboy is the one which gets most use around here, followed by Logic’s stereo and Tape delay: simple but effective."

Used on Purpose, as stated by mix engineers Josh Gudwin and Andrew Wuepper in this May 2016 Sound on Sound interview about the mixing of the title track and others.

Gudwin picks out a few other interesting tracks, beginning with a vocal track named ‘vcls’. “That track contains a vocal sample that Blood made of Justin’s vocal. I’m just touching that with the LFO Tool for a bit of pumping, I take out some high frequencies with the Pro-Q 2, and then use the SoundToys Microshift for a slight pitch-shift/chorusing effect. ‘Sry1V’ below that is the vinyl sound in the track. ‘$JBU’ is the main lead vocal bus, on which I have the UAD 1176, Waves De-Esser, Manley Massive Passive, Metric Halo Channel Strip. The sends are to the generic aux tracks at the bottom of the sesion: verb, ping-pong delay, Dimension D. Below the lead vocal bus is the print track of a Bricasti outboard.”

Wuepper: “There are two tracks called ‘Bric’ around the main vocal bus; the one above is the print from the Bricasti effect that was used on the percussion, and the one below is the print of the Bricasti reverb on the vocal. Next are Josh’s vocal delays. Putting delays on audio snippets [ie. copying short vocal clips to new tracks and applying delays as inserts, rather than automating a send from the main vocal track] is a pretty interesting way of doing things. I’ve not seen anyone else do this, but it makes it easier for Josh to manipulate these delays and to go deeper into the effect. He can really fine tune the delay times and decay lengths and so on. Sometimes the feedback you get with plug-ins can act a little weird, and this approach allows him to have more control.”

Gudwin: “The five green tracks are all vocal throws and delays. I don’t like to automate delay throws via aux tracks. The top green track is the master track for the delays, ‘JB Throw All’, and it has a compressor and an SPL Vitalizer. The ‘1147’ delay track has the UAD Cooper Time Cube, with a quick ping-pong-y flutter delay that I use to widen, and the track called ‘1167’ has a basic eighth-note delay from the Echo Boy. The ‘A’ insert is Auto-Tune, but it’s not working on these tracks. When needed, our vocal tuning is normally done by Chris ‘Tek’ O’Ryan in Melodyne. I sometimes do it myself, if I have the time do it, in the stand-alone version.

“The blue vocal tracks below the vocal delay tracks are the main lead vocal comp tracks, and on many of them I have the UAD SSL Channel Strip, UAD LA-2A, and the Waves C6 multiband compressor, and sometimes also the Pro-Q 2 EQ. The ‘DLYP’ track has a delay pan effect, with the SoundToys Primal Tap delay and Panman auto-panner, SSL Channel Strip and the P&M Vinylizer. ‘White’ and ‘Master’ are printed reverbs recorded in two rooms at Henson. They are my main plug-in vocal reverbs, and the green tracks below are pitched with the Elastic Audio X-Form [in Pro Tools] and effected with the Waves H-Compressor for a pumping effect. I pitched the reverbs up an octave or two, and I mixed them in very low. The ‘PCM’ and ‘PC1’ tracks are prints from ping-pong delays from the Lexicon PCM42 outboard.

“Justin’s backing vocal tracks all go to the group track called ‘JBG1’, on which I have a Waves De-esser, an SSL Channel and the C6 multiband compressor, plus there are a number of delays and reverbs via the sends. Trevon’s backing vocals all go to ‘JBTR’, which has similar effects. I wanted to fill the song up a bit more, and sometimes it’s not the most enjoyable process for an artist to sing all these background parts. Plus a different vocalist will add a different texture to the song, as long as it complements the lead vocal and the record. As I mentioned, Julia added her vocals during the final mix in New York, and her group track also has the De-esser, SSl Channel and C6. Right at the bottom are some effects tracks, with the Dimension D and group delay throws, and so on.

(...) 'Love Yourself'

(...) Next are Justin’s vocals, with I overdubbed in New York. Almost all the regular vocal tracks have the UAD SSL Channel, LA2 and the Waves C6 multiband compressor. These three plug-ins work great on his vocals, so I tend to stick with them. Each of the vocal tracks has slightly different settings from them. They all go to Justin’s lead vocal bus above them, which has the FabFilter Pro-DS de-esser and the Pro-2 EQ. Justin’s lead vocals also go through the Bricasti, and the effect is printed. My own four backing vocals went through a vocal bus on which I had the SSL Channel, and a compressor, but they didn’t do much, nor did the sends. These vocals are very much in the background, I just wanted to add some texture really quickly. Finally, at the top of the session everything went through a Master track, on which I had the UAD SSL channel, mainly for compression set to mid-attack and auto-release — without drums you don’t need the slow attack and quick release — a Massey EQ, boosting 100Hz and 16kHz, a FabFilter Pro-L for level, and the Sonnox Oxford Inflator to add some sheen.”

'What Do You Mean?'

(...) “There were a few more complicated vocal effects, like the ‘JG FX’ track, on which I used the Vitalizer doing some spatial expanding, a UAD Fatso to thicken it up, and I then cut some low mids with an EQ, and used a de-esser. This effect track gave more depth to the vocal and made him sound more like an angel! Underneath that are two ‘Radio’ tracks [which sound like they could have come straight from Peter Gabriel’s ’80s Fairlight experiments]. I used Auto-Tune to pitch the vocals up, and then put on a SoundToys AlterBoy, which changed the formant, and then I’m filtering 350Hz and below.

“Below the ‘radio’ tracks are all my vocal delay tracks, in green as usual, with the bus for all delay throws at the top. One delay track, ‘Splaater’, is a flutter delay with Auto-Tune and the Cooper Time Cube, and the other two have the Waves H-Delay and SoundToys Echo Boy. They’re both quarter-note delays, but with different feels. Below the delay tracks are some ad lib tracks, and all the actual lead vocals, pulled out over several tracks. Most of them have my regular trio of UAD SSL Channel, LA2 and Waves C6 plug-ins, and all vocals are sent to the ‘JB Buss’, on which I have the FabFilter DS de-esser, a Manley EQ doing light cuts at 330Hz, 560Hz and 3kHz, and then a whole bunch of sends to my regular aux tracks at the bottom: a hall reverb, a plate reverb, a light quarter-inch delay, a light ping-pong delay and a Dimension D.

“Further down are four Justin backing vocal tracks, which go to a bus above them, ‘JBG1’, on which I have the SSL Channel, boosting highs and cutting lows and doing some heavy compression, a UAD 33609 compressor, and then the Waves Enigma [phaser/flanger] on a Mutron setting, adding some sweeping sounds. The sends are once again hall and plate reverbs, a quarter-note and a ping-pong delay and a UAD Roland Dimension D. Once Justin had decided to go with my rough mix, I spent another half hour on it, doing some EQ adjustments, and that was it.”
