The first version of this guide went up in 2022, and looking back, it was pretty thin. This is the full 2026 rewrite: everything I actually do to keep my own mixes clean, with concrete numbers you can lift straight into your sessions.
Let me say this up front: no single magic plugin produces a clean mix. It’s a chain of small calls: which sounds you pick, levels, EQ, compression, space. Get each link roughly right and the mix largely cleans itself.
Clean starts before the mix
The worst mixing mistake happens before mixing even begins: choosing sounds that clash, then throwing EQ at the wreckage.
So before any fader moves, play your sounds together and listen. Two synths sitting in the same frequency range at the same time? One of them changes: new octave, new patch, or out entirely. A few strong layers beat a wall of average ones every single time.
The quality of the source counts just as much. A properly designed preset arrives with the low end already filtered and the harshness already handled, which leaves you less to repair. That’s more or less why making presets is my job. On Serum 2? Take our free Serum 2 presets pack: 250+ patches, each one tested inside a full mix rather than soloed in isolation. Need broader coverage? The Serum 2 preset bundles span basses, leads, pads and keys across most genres.
Drums follow the same logic: a clean sample barely needs processing. A pack like Drums Utopia Vol.1 comes pre-balanced, meaning you’re mixing rather than performing rescue work.
Gain staging: the boring step that fixes everything
The majority of muddy, harsh mixes share one cause: everything’s running too hot. Clipping digitally inside a plugin chain bakes in distortion you can’t remove later, and a slammed master bus smears the whole thing together.
Here’s what I do:
- Target roughly -18 dBFS average per track, with peaks near -10. Plugins modeled on analog hardware are happiest right there.
- Begin the mix with all faders pulled down. Bring up the most important element first (usually kick or vocal) and balance the rest against it.
- Keep around 6 dB of headroom on the master, and no limiter on it while mixing.
Nothing more than this, and your mix already beats 80% of the demos landing in my inbox.
EQ: cut before you boost
EQ is where a clean mix gets made or destroyed. The rule that turned my mixes around: narrow cuts, wide boosts — and cuts come first.
- High-pass almost everything. Pads, hats, guitars, vocals: everything below 80–120 Hz goes. That rumble carries zero music and burns headroom. The sub range belongs to kick and bass alone.
- Mud lives at 200–400 Hz. Mix sounding thick and cloudy? Sweep a narrow cut through this band on your busiest tracks. Pulling 2–4 dB from two or three tracks usually does it.
- Boxiness sits at 400–600 Hz, harshness at 2–5 kHz. Identical technique: narrow cut, sweep around, locate the ugly spot, remove a few dB.
- One sound per zone. Choose who owns the sub, who owns the low mids, who owns the top. Everyone else gets carved away from that territory.
The kick-versus-bass battle earns its own line: decide which of the two owns 40–60 Hz, pull the loser down 3–4 dB in that range, or sidechain bass to kick. That one move de-muds more low ends than any “mastering chain” ever has.
Worth knowing: a lot of this shaping belongs inside the synth rather than on the channel. Serum 2’s filters and per-patch EQ let you repair a patch at the source; full breakdown in my Serum 2 filters guide. And when your 808s keep turning into soup, the Serum 2 808 bass tutorial handles tuning and saturation so the sub still reads on small speakers.
For reference, here’s a clean, pre-processed 808; note how nothing needs fixing:
Compression: control, don’t crush
What compression does is even out levels: quiet details stay hearable, loud peaks stop jumping out. Applied gently, it tidies a mix. Applied hard, you get the opposite: pumping, dullness, noise dragged up between notes.
Settings that work as a starting point on most material:
- Ratio somewhere from 2:1 to 4:1.
- Attack at 10–30 ms, letting transients punch through. Anything under 5 ms flattens drums, so do that deliberately or not at all.
- Release near 100 ms, or auto where available.
- Shoot for 2–4 dB of gain reduction on the loud sections. A meter reading 10 dB means the threshold needs backing off.
When one compressor won’t cut it, run two at 2–3 dB apiece rather than one doing 6. Serial compression comes out smoother and stays invisible.
Reverb and delay: space without the wash
Reverb adds size — and drowns mixes faster than anything else. Three habits keep it under control:
- Use sends, not inserts. One or two shared reverbs bind the mix together and stay manageable. A separate reverb per track is chaos.
- EQ the reverb return. High-pass around 300–400 Hz, low-pass near 8 kHz. Reverb in the low frequencies is mud, full stop; you won’t miss it once it’s gone.
- Set 20–40 ms of pre-delay. Dry transient first, tail second. The source stays forward and defined even with plenty of reverb behind it.
Delay is frequently the cleaner tool anyway: a tempo-synced 1/4 or 1/8 with feedback at 20–30% gives depth without a permanent tail. Key a sidechain compressor off the dry signal to duck the delay, and it only blooms in the spaces.
Building your space inside Serum 2 instead? It’s had full FX buses since the 2025 update, and my Serum 2 effects guide covers keeping patch reverb out of a fight with your mix reverb.
Panning and the mono check
Width is separation you get for free. Kick, bass, snare and lead vocal stay dead center. Supporting parts move outward: doubled guitars hard left and hard right, hats and percussion around 30–50%, pads spread wide.
Two rules keep the image clean:
- When two sounds mask each other, separate them with panning before touching EQ. Opposite sides, done.
- Once per session, listen in mono. Phones, club rigs and Bluetooth speakers collapse stereo constantly; anything that disappears in mono needs its phase or widener fixed, not its volume.
Check your mix on more than one system
Clean on your headphones only means clean on your headphones. Nothing leaves my studio until it’s been through monitors at low volume, cheap earbuds, a phone speaker and the car. Each reveals something the others hide: the phone tells you whether the melody survives with no sub, the car exposes low-mid buildup, quiet monitoring shows you the honest balance.
Low volume is the real secret weapon. A mix that balances at whisper level will sound great loud. It never works the other way around.
And when the same issues return mix after mix, the root cause usually sits upstream in the sound design; I rounded up the usual suspects in Serum 2 beginner mistakes.
FAQ: getting a clean sound
Why does my mix sound muddy?
Nine times out of ten: excess energy at 200–400 Hz combined with unfiltered lows on tracks that don’t need them. High-pass everything but kick and bass, then run a narrow cut through the low mids of your densest tracks. Ten minutes, most of the mud gone.
Should I EQ before or after compression?
Remove problem frequencies ahead of the compressor so it isn’t reacting to rumble and mud you were cutting anyway. Tonal boosts come out smoother post-compression. EQ → compressor → EQ is a perfectly normal chain.
Do I need expensive plugins for a clean mix?
Not at all. The stock EQ and compressor in any current DAW are transparent and plenty capable. Clean mixes come out of gain staging, cuts and arrangement calls, never out of a $300 model of a 1970s console.
How loud should my master be while mixing?
Hold roughly 6 dB of headroom and leave the limiter off until the mix is done. Loudness belongs to mastering. Chase volume during mixing and every balance decision you make is based on distortion rather than the mix itself.
And that’s the entire system. Nothing exotic here — boring fundamentals, applied consistently, in order. If you’d rather start from sounds that show up clean instead of needing rescue, the free Serum 2 presets pack is the easiest entry point: 250+ patches, free, ready for a mix out of the box.
I run Monosounds.studio and make the packs myself. Ten-plus years of producing, 97+ releases, 16,000+ downloads. Every Serum 2 preset we ship passes a CPU check on a mid-range laptop and gets used in a real track before release. If it does not survive a mix, it does not go in the pack.
