Humanity’s Last Breath: Brutal Amp Sim Tones & DI Sculpting

When you think of Humanity’s Last Breath, you think of guitar tones that are, frankly, ridiculously heavy. That crushing, tectonic-plate-shifting sound is a hallmark, and a huge part of it comes down to how mastermind Buster Odeholm dials in his guitars. Ever wondered how to get that kind of modern metal brutality using amp sims? Well, you’re in luck. We’re diving into Buster’s approach, showing you how he crafts these tones, focusing on amp sims and some seriously smart DI signal manipulation.

This isn’t just about slapping on a high-gain plugin and calling it a day. It’s about meticulous shaping before you even hit the virtual amp. As Buster himself will tell you, a great DI is paramount. And if you’re serious about leveling up your own productions, understanding these nuanced techniques from top-tier producers is invaluable. That’s exactly what Nail The Mix is all about – learning directly from the pros who craft the sounds you love. You can check out this full session here. Let’s dive in!

The Golden Rule: Your DI is Everything

Before we even talk amp sims, let’s hammer this home: the quality and character of your Direct Input (DI) signal are foundational. Buster emphasizes this – a stellar DI will sound good through almost anything. His process for achieving that monstrous Humanity’s Last Breath sound heavily involves treating the DI signal before it even sees an amp sim. This upfront shaping is where much of the magic happens.

Buster’s Amp Sim Arsenal & Signal Chain

For this particular tone-crafting session, Buster leans on a few key digital tools. Here’s a look at his preferred setup:

H3: The Amp Head: Neural DSP Nameless

No surprises here for fans of modern metal tones. Buster reaches for the Neural DSP Nameless Suite, but with a specific focus: he’s only using the amp head section. The built-in pedal and cab sections are bypassed for this chain. This allows for more surgical control by using dedicated tools for those jobs.

H3: Cab Simulation: TSE Audio TSC & Ryan Harvey IRs

For cabinet emulation, Buster’s choice is the TSE Audio TSC. Specifically, he loads up the Ryan Harvey signature IRs (Impulse Responses). Why these? He describes them as “super subby,” delivering that immense low-end foundation crucial for the HLB sound. This is the same cab setup he used on the album, so you know it’s legit.

H3: The Boost Pedal Twist: Parallel Power with Blue Cat Audio PatchWork

Here’s a clever bit of routing. Instead of putting a boost pedal directly in series, Buster uses Blue Cat Audio’s PatchWork (or a similar parallel processing plugin) to load the TSE Audio TSC (likely meaning the TSE 808 or a similar boost pedal plugin, though he mentions TSC again in the context of parallel processing for a boost effect). The key reason for this is to utilize PatchWork’s mix knob. This allows him to blend in the perfect amount of the boost pedal’s effect, rather than having it at 100% all the time. He often sticks to a standard boost setting and then dials in the overall intensity with that parallel mix control.

Pre-Amp Sculpting: The Art of DI Manipulation

This is where Buster’s approach really shines. He’s a big proponent of EQing the DI before the amp and after the boost. As he puts it, “the amp will react a certain way to frequencies. So just fuck with the frequencies and you’ll get what you want.”

H4: Initial Compression for Even Dynamics

To tame the sometimes wild dynamics of heavily pitched-down guitars, Buster inserts a compressor early in the chain (after the boost but before the main pre-amp EQ). This helps even out the signal, ensuring the amp sim gets a more consistent input, which is especially useful for those low, chuggy riffs where string attack can vary wildly.

H4: EQing the DI: Taming Fizz and Accentuating “The G”

With a FabFilter Pro-Q 3 (or your EQ of choice) inserted before the amp sim, Buster gets surgical:

• Input Dialing: He often starts by “learning” the input to get a baseline.
• Tackling “Scratchiness”: He identifies and pulls down those harsh, scratchy high frequencies that can make a distorted tone sound fizzy or thin. This isn’t about a broad treble cut, but a more focused reduction of unpleasant artifacts, often found in the upper-mids or lower treble. This makes the distortion character smoother and more pleasant.
• Boosting for “G”: To get that characteristic djenty “G” sound (that percussive, articulate attack), he’ll boost the very high “scratchy” frequencies. Be warned, this can introduce noise, so it’s a balancing act.
• Low-End Bloom Control: If the low-end starts to get too boomy or overwhelming (“blooms a bit too much”), he’ll use a dynamic EQ to selectively tame those problematic frequencies only when they exceed a certain threshold. This keeps the low-end powerful but controlled. Dive deeper into EQ strategies for mixing modern metal to master these techniques.
• Strategic Mid-Cuts (For Now): He might also introduce some mid-cuts at this stage, knowing he can add desirable mid-frequencies back in later with other tools.

The “Makes Everything Better” Plugin: FabFilter Saturn

After the amp and cab sim, Buster often turns to FabFilter Saturn 2. This saturation and distortion plugin is his go-to for adding that final layer of polish and character. He uses it to:

• Enhance Mids: If he’s scooped mids earlier, Saturn can help reintroduce them in a pleasing, harmonically rich way.
• Fill Frequency Gaps: Observing the spectrum, he can use Saturn to subtly fill in dips, making the tone fuller and more robust.
• Add Vibe: Ultimately, Saturn just “makes everything better” by adding a certain vibe and cohesion to the guitar tone.

Key Takeaways for Your Own Ridiculously Heavy Tones

Buster Odeholm’s method for achieving Humanity’s Last Breath’s monumental guitar sound is a masterclass in meticulous signal shaping. Here are the core principles you can apply to your own productions:

1. DI is King: Start with the best possible DI recording.
2. Pre-Amp EQ is Your Friend: Don’t just rely on the amp sim’s EQ. Shape your DI signal before it hits the amp to dictate how the amp reacts.
3. Parallel Processing for Control: Experiment with parallel processing for effects like boost pedals to get precise blend control.
4. Dynamic Control is Key: Use compressors and dynamic EQs to manage unruly frequencies and dynamics.
5. Saturation for Polish: Leverage saturation plugins like FabFilter Saturn to add warmth, character, and fill out the tone.

Crafting these kinds of tones takes practice and a deep understanding of how each processor affects the signal. Watching a pro like Buster Odeholm work through these steps, explaining his thought process, is an incredible learning opportunity.
