How to Get a Spiritbox Guitar Tone with Quad Cortex
Want to get the crushing, modern guitar tones heard in Spiritbox using the Neural DSP Quad Cortex?
Spiritbox has become one of the defining bands in modern metal, combining aggressive low-tuned guitar riffs with atmospheric cleans, massive choruses, and dynamic heavy sections.
Guitarist Mike Stringer has developed a distinctive sound built around tight low-end response, aggressive distortion, melodic guitar parts, and carefully layered production.
One amplifier particularly worth exploring for this style is the Omega Ampworks Granophyre. Mike Stringer has previously discussed using a Quad Cortex with a capture of this amplifier.
With the right Neural Captures, cabinet choices, and effects, you can build your own Spiritbox-inspired guitar tones using the Quad Cortex.
In this guide, we'll look at the sound, the amplifiers worth exploring, and how to create a versatile modern metal preset.

What Makes the Spiritbox Guitar Tone So Distinctive?
Spiritbox's guitar sound combines several different tonal characteristics.
The heavy sections are aggressive, tight, and powerful, while the cleaner sections introduce atmosphere, space, and contrast.
Some of the defining characteristics include:
Low-tuned 7-string and 8-string guitars
Tight, aggressive high-gain rhythm tones
Strong midrange definition
Clear low-frequency response
Atmospheric clean guitar sounds
Wide stereo rhythm guitar production
Dynamic transitions between heavy and melodic sections
The important thing is versatility.
A good Spiritbox-inspired preset should be capable of producing aggressive rhythm tones without making the cleaner sections sound lifeless or overly processed.
The Omega Granophyre: A Great Starting Point
The Omega Ampworks Granophyre is an excellent amplifier to explore when building a Spiritbox-inspired modern metal tone.
Mike Stringer has previously discussed using a Quad Cortex with a capture of an Omega Granophyre amplifier.
The Granophyre is known for its aggressive high-gain character, tight response, and strong articulation.
Its tonal characteristics make it useful for:
Modern metal rhythm guitar
Metalcore
Progressive metal
Low-tuned guitar riffs
Aggressive palm-muted patterns
High-gain lead tones
For Quad Cortex users, a Neural Capture of the Granophyre provides a convenient starting point for building this style of guitar tone.
It's not a guarantee of an exact Spiritbox recording tone, but it's a very relevant amplifier to explore.
How to Get a Spiritbox-Inspired Tone Using Quad Cortex
The easiest way to get started is with a high-quality Neural Capture of the Omega Granophyre.
From there, you can build a signal chain that gives you tight rhythm tones, aggressive leads, and atmospheric clean sounds.
1. Start With an Omega Granophyre Capture
Begin with a D.I. capture of the Omega Granophyre.
This gives you the amplifier's core tonal character while allowing you to experiment with different cabinet IRs or Quad Cortex cabinet blocks.
Start with the capture before making major EQ adjustments.
Listen for:
Tight palm mutes
Aggressive midrange
Defined low notes
Clear pick attack
Good note separation
The goal is to get a powerful rhythm tone without excessive distortion.
2. Add an Overdrive or Boost
A boost in front of a high-gain amplifier can help tighten the low end and make palm-muted riffs more aggressive.
A Tube Screamer-style overdrive or Precision Drive-style boost is a good place to start.
Try these general settings:
Gain: Low
Level: Moderately high
Tone: Adjust to your pickups and cabinet
Bass: Avoid excessive low frequencies entering the amp
The boost should tighten the response rather than add unnecessary distortion.
3. Choose a Suitable Cabinet
If you're using a D.I. Neural Capture, you'll need a cabinet stage to complete the 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.
A good cabinet choice can make a significant difference in how aggressive, bright, or dark your guitar tone sounds.
If you're using a full-rig capture, it may already contain the cabinet and microphone coloration. Avoid adding another cabinet stage unless you intentionally want to experiment.
4. Shape the Midrange
A strong midrange helps modern metal guitar tones remain present in a dense mix.
Avoid scooping too much of the midrange.
Instead, focus on finding a balance between aggressive upper mids and enough body in the lower mids.
If the guitar sounds harsh, experiment with reducing the most unpleasant high-mid frequencies rather than cutting all the presence.
5. Control the Low End
Low-tuned guitar requires careful low-frequency management.
If your palm mutes sound loose or muddy, try:
Reducing excessive bass before the amp
Adjusting the cabinet IR
Using a boost
Reducing unnecessary gain
Applying subtle post-capture EQ
The bass guitar should provide much of the low-frequency weight in the final mix.
Your guitar needs to remain tight and articulate.
6. Build a Separate Clean or Ambient Scene
One of the most important parts of a Spiritbox-inspired sound is the contrast between heavy and atmospheric sections.
Rather than trying to make one high-gain sound handle everything, build separate scenes or presets.
For a clean scene, experiment with:
A clean amplifier or clean capture
Chorus or modulation
Delay
Reverb
Volume control
Subtle compression
You can use the Quad Cortex to switch between heavy and clean sounds without having to rebuild your signal chain during a performance.
Recommended Quad Cortex Signal Chain
Here's a practical starting point for a Spiritbox-inspired high-gain rhythm preset.
High-Gain Rhythm Chain
Noise Gate
Overdrive / Boost
Omega Granophyre Neural Capture
Cabinet IR or Cab Block
Post-EQ
Output
Atmospheric Clean Chain
Compressor
Clean Amp or Capture
Chorus / Modulation
Delay
Reverb
Output
You can organize these sounds into separate scenes or presets depending on how you prefer to perform.
The important thing is having the right sound available for each part of the song.
Other Amplifiers Worth Trying for Spiritbox-Inspired Tones
The Omega Granophyre is a particularly relevant starting point, but there are several other high-gain amplifiers worth exploring.
Fortin Evil Pumpkin
A strong option for aggressive modern metal rhythm tones.
Try it when you want a tight, saturated sound with plenty of attack.
Driftwood Purple Nightmare
A great option for thick, aggressive high-gain tones with a powerful low end.
RedSeven Leviathan
Worth exploring for aggressive rhythm guitar, tight low-tuned riffs, and modern high-gain applications.
Randall Satan
An interesting option for aggressive modern metal and low-tuned rhythm guitar.
Omega Obsidian 1.5
Another Omega amplifier worth comparing against the Granophyre.
Experiment with both to find the response and tonal character that best suits your playing style.

How to Make Your Spiritbox-Inspired Tone Sound Better in a Mix
A great guitar tone by itself doesn't always translate into a great recorded guitar tone.
Spiritbox's production combines aggressive guitars with bass, drums, vocals, and atmospheric elements.
Here are some 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 a wide stereo image and helps the guitars sound bigger without simply increasing their volume.
Keep the Low End Controlled
Avoid adding too much bass to your guitar tone.
Low-tuned guitars already produce substantial low-frequency energy.
Let the bass guitar provide the additional 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
Ambient textures
This gives you much more control over the dynamics of a performance.
Don't Overdo the Gain
Excessive distortion can make the guitar sound smaller in a mix by reducing note separation.
Start with enough gain to get the aggression you want, then adjust based on how the guitar performs alongside the drums and bass.
Make Room for the Vocals
Modern metal mixes can become crowded very quickly.
Avoid excessive upper-midrange buildup that competes with the vocal.
A balanced guitar tone will sound heavier and more professional once everything is playing together.
