What Makes the Sleep Token Guitar Tone So Distinctive?

Sleep Token's guitar sound is built around contrast.

Some sections feature extremely heavy, low-tuned guitar riffs, while others use clean tones, ambient effects, and spacious production.

The defining characteristics include:

  • Extremely low guitar tunings

  • Aggressive, tight high-gain rhythm tones

  • Extended-range and baritone guitars

  • Strong low-frequency response

  • Clear note definition

  • Atmospheric clean guitar sounds

  • Delay and reverb effects

  • Wide stereo guitar production

The goal isn't simply to create the heaviest possible distortion.

You need a guitar tone that can deliver powerful low-end riffs while remaining clear and articulate. You also need a completely different sound for the atmospheric sections.

That's why building separate Quad Cortex scenes for heavy and clean sounds is a great approach.

What Gear Does Sleep Token Guitarist IV Use?

One of the most interesting aspects of Sleep Token's guitar setup is the way IV combines extended-range guitars with digital modeling.

In a December 2024 Guitar World rig rundown, IV's guitar technician revealed several details about the live setup.

Some of the key details included:

  • Neural DSP Quad Cortex processors

  • Revv Generator amplifier captures

  • Mesa cabinet captures

  • Two amplifier tones running left and right

  • MIDI control of the processors

  • The Quad Cortex Doubler feature for additional stereo width

The technician explained that IV's main tones came from a Revv Generator amplifier and Mesa cabinet captured into the Quad Cortex.

This is a particularly interesting approach because it combines the character of a real amplifier and cabinet with the flexibility of digital modeling.

Important: The Revv Generator is part of IV's documented setup, but it isn't included in the Strange Angles Music packs featured below. We'll explore alternative high-gain captures that you can use to build your own version of this sound.

The Sleep Token Guitar: Low Tunings and Extended Scale Lengths

Another important part of the band's sound is the guitar itself.

IV has used extended-range guitars, including an unusual 30-inch-scale baritone guitar.

This allows for extremely low tunings while maintaining better string tension than a conventional guitar.

For example, the tuning used for the 8-string parts in "The Summoning" is an unusually low tuning:

Low to high: E – A – E – A – D – G – B – E

The arrangement also uses digital pitch shifting, so the recorded and performed pitch relationship is more involved than simply tuning an ordinary 8-string down.

You don't necessarily need a 30-inch baritone to experiment with this sound, but guitar setup becomes increasingly important as you go lower.

Consider:

  • Appropriate string gauges

  • Sufficient scale length

  • Proper intonation

  • Pickup clarity

  • Consistent picking technique

A guitar with insufficient string tension can make low notes sound loose and difficult to control.

How to Get a Sleep Token-Inspired Tone Using Quad Cortex

You don't need the exact Revv Generator setup to build a similar tonal character.

The Quad Cortex gives you plenty of flexibility to experiment with different high-gain amplifier captures, cabinet IRs, and effects.

Here is how I'd approach the setup.

1. Start With a High-Gain Amplifier Capture

For the heavy sections, start with an aggressive high-gain capture.

Some good options available through Strange Angles Music include:

  • Omega Granophyre

  • Fortin Evil Pumpkin

  • EVH 5150 III

  • Omega Obsidian 1.5

  • Driftwood Purple Nightmare

The Omega Granophyre is a particularly interesting starting point for modern metal because of its aggressive character and tight response.

The Fortin Evil Pumpkin is another great option if you want a saturated, aggressive rhythm tone.

These aren't Revv Generator recreations. They're alternative amplifier tones that you can use to build your own Sleep Token-inspired sound.

2. Add an Overdrive or Boost

A boost can help tighten the low end and improve the attack of a high-gain amplifier.

A Tube Screamer-style overdrive or Precision Drive-style boost is a good starting point.

Try these general settings:

  • Gain: Low

  • Level: Moderately high

  • Tone: Adjust to your pickups and cabinet

  • Bass: Avoid excessive low frequencies

Don't automatically add an overdrive to every capture. Some amplifiers already have the tight response you're looking for.

3. Choose the Right Cabinet

The cabinet has a major influence on the final guitar tone.

A 4x12 cabinet with Celestion Vintage 30-style speakers is a useful starting point for modern metal.

Experiment with different microphone positions and blends.

If you're using a D.I. capture, add a cabinet IR or cabinet block to complete the sound.

If you're using a full-rig capture, it may already include cabinet and microphone coloration. Avoid adding another cabinet stage unless you're deliberately changing the sound.

4. Keep the Low End Controlled

Low-tuned guitars can quickly become muddy if there's too much bass going into the amplifier.

If your palm mutes sound loose, try:

  • Reducing excessive bass before the amp

  • Using a suitable boost

  • Adjusting your cabinet IR

  • Reducing unnecessary gain

  • Applying subtle post-capture EQ

Let the bass guitar provide much of the low-frequency weight in the mix.

Your guitar needs to remain tight and articulate.

5. Use Stereo Processing for Wider Guitar Sounds

One interesting detail about IV's documented Quad Cortex setup is the use of two amplifier tones running left and right.

You can experiment with a similar concept in your own recordings.

Try using:

  • Two different amplifier captures

  • Different cabinet combinations

  • Separate left and right guitar recordings

  • Subtle stereo processing

  • The Quad Cortex Doubler feature where appropriate

For recorded rhythm guitars, two separate performances panned left and right are still an excellent starting point.

Avoid simply duplicating one mono recording and expecting it to create the same width.

How to Create Sleep Token-Style Clean and Atmospheric Tones

The atmospheric side of Sleep Token is just as important as the heavy guitar sound.

Rather than trying to use one high-gain preset for everything, create a separate clean scene.

1. Start With a Clean Amplifier

Choose a clean amp or clean capture with enough headroom to keep the sound clear.

Avoid excessive distortion or compression.

2. Add Chorus or Modulation

Subtle modulation can add movement and width to clean guitar sounds.

Start with a moderate chorus setting and adjust the depth and rate until the sound feels natural.

3. Add Delay

Delay is useful for creating spacious guitar textures.

Experiment with:

  • Quarter-note delay

  • Dotted-eighth delay

  • Longer ambient delays

  • Increased feedback for atmospheric sections

Keep the effect level appropriate for the part you're playing.

4. Add Reverb

Reverb is essential for creating large, atmospheric guitar sounds.

Try:

  • Hall reverb

  • Plate reverb

  • Ambient reverb

  • Longer decay times

For atmospheric sections, longer decay times can help create a much larger sense of space.

5. Create Separate Quad Cortex Scenes

Organize your sounds into separate scenes so you can switch between them during a performance.

This gives you a versatile setup for moving between crushing metal riffs and spacious atmospheric passages.

How to Make Your Sleep Token-Inspired Tone Sound Better in a Mix

A great guitar tone by itself doesn't always translate into a great recorded guitar tone.

Sleep Token's production combines guitars with bass, drums, vocals, synthesizers, and atmospheric elements.

Here are a few practical tips.

Double-Track Your Rhythm Guitars

Record two separate performances of the same rhythm part.

Pan one performance left and the other right.

This creates natural stereo width and helps the guitars sound much bigger.

Keep the Low End Controlled

Low-tuned guitars already produce substantial low-frequency energy.

Avoid excessive bass in your guitar signal.

Let the bass guitar provide additional low-frequency weight while the guitars focus on attack, definition, and midrange.

Use Different Tones for Different Sections

Don't force one high-gain preset to handle every part of a song.

Use separate scenes for:

  • Heavy rhythm guitar

  • Lead guitar

  • Clean guitar

  • Atmospheric textures

This gives you much more control over the dynamics of a performance.

Don't Overdo the Gain

Excessive distortion can reduce note separation and make complex riffs sound less precise.

Start with enough gain to get the aggression you want, then adjust based on how the guitar performs alongside the drums and bass.

Leave Space for the Other Instruments

One of the defining characteristics of Sleep Token's production is the contrast between different musical elements.

Avoid filling every available frequency with guitar.

A controlled guitar tone leaves more room for the bass, vocals, synthesizers, and other atmospheric elements.
