Maxim here. I run Monosounds and I’ve made my living building Serum preset packs since 2017. No sound gets me more questions than bass, so this whole guide is low end: the patch types you genuinely need, settings that hold up in practice, and the packs actually worth paying for in 2026.
One version note before we start. Everything below targets Xfer Serum 2, the free upgrade that landed for Serum 1 owners in March 2025. Our packs all load in it without issue, and several of these bass tricks got far easier thanks to the new engines. Still weighing the update? My full comparison lives in Serum 1 vs Serum 2.
What Serum 2 changed for bass
Serum 2 is more than a fresh coat of paint. Where bass is concerned, three changes count.
Three oscillators instead of two. A clean sine sub can now live on osc C while A and B carry the mid-range character. You stop sacrificing the noise osc, and you stop stacking instances just to protect the low end.
Five synthesis engines. Wavetable remains the default, but granular and spectral shine as gritty texture layers over a bass. Try a slow granular scan across a vocal sample, low-passed near 800 Hz, for a nasty mid-bass layer, in the good way.
New FX buses. Sub and mid layer can run through their own effect chains inside a single patch. Mids get distortion and chorus, sub gets nothing. That workflow used to demand two synth instances plus a mixer bus; it’s one preset now.
Preset designers who know their craft exploit all three, and it’s why a properly built 2026 bass patch sounds cleaner and drops into a mix quicker than most older ones.
The bass types every producer needs
Every genre leans on its own flavour of low end. This is what I’d expect from any serious library, along with the settings I actually run.
Sub bass
The foundation layer. A single sine or slightly rounded triangle, mono under 120 Hz, and never, ever, reverb. When the sub feels thin on small speakers, resist boosting the lows: a hint of saturation puts harmonics at 100–300 Hz that carry the note instead. In Serum 2 the Tube distortion at 10–15% drive usually does it.
Reese bass
A pair of saws detuned somewhere around 15–25 cents, run through a low-pass, with the width confined to the mids. That’s the classic drum and bass engine. With Serum 2’s third oscillator you can park a locked sine beneath the detuned pair: the mids swirl while the low end never budges. Our Epic Tones drum and bass presets follow exactly this construction.
Growls and FM bass
The talky, aggressive territory of dubstep, riddim and bass house. Core recipe: FM a modulator osc into a harmonically dense wavetable, put an LFO or notepad envelope on wavetable position, then hit it with heavy post-distortion. The vocal quality comes from formant filters sweeping between vowel shapes like “oo” and “ah”. Want to build your own? The Serum 2 growl tutorial takes the whole workflow apart step by step.
808-style bass
Trap, drill, modern pop. A proper 808 preset carries a pitch envelope on the attack (a quick 12–24 semitone drop over 30–60 ms), a long amp release, and glide around 50–80 ms for the sliding lines. With distortion, the type beats the amount: Warm Drive stays round, Hard Clip makes it knock. Tuning and slides get more coverage in my Serum 2 808 guide.
House and slap bass
The rolling basslines of tech house, deep house and slap house. These sit in the 60–250 Hz pocket and want a fast, clicky attack to punch through a crowded drum groove. Sidechain is baked into the aesthetic; most of our house bass presets include a macro that fakes the pump so you can skip routing a compressor.
The bass packs I’d actually recommend
Full disclosure: these are my own packs, so of course I’m biased. They’re also the ones customers reorder most, and every demo below is the raw preset, zero post-processing.
Start free. The Free Serum 2 Bass Presets come first. It’s a small pack, but subs, a reese and a couple of mid-bass patches , enough to tell you whether our design style suits you before any money changes hands.
For slap house and EDM: Slap House Serum 2 Presets. Big bouncy basses in the Imanbek and VIZE lane, each with brightness and drive macros so a single preset serves both the drop and the breakdown.
For trap and hip-hop: Synopsis 808 Presets. Forty-plus 808s with the glide and pitch envelopes already set. Load, play, move on.
For heavier bass music: the Skrillex-inspired Grumble pack. Growls, screeches and formant basses, wavetable movement wired to macros, so resampling your own variations goes fast.
For club and tech house: Fishlake Vol.2 tech house presets. Tight groove-ready basses that already lock against a 128 BPM kick. And if warmer basslines and stabs are more your thing, there’s a solid deeper selection in Modern Deep House Vol.1.
How to judge a bass preset pack
Things I’d verify before handing anyone money for a pack, mine included.
Mono-compatible low end. Sum your master to mono. Bass gone? The designer spread stereo width across the sub. Rookie move, and on a club rig it destroys the patch.
Macros that do something musical. A good pack maps macros to what you’d genuinely automate: drive, brightness, movement, width. Empty or purely cosmetic macros mean the designer was in a hurry.
Raw demos. When every demo hides inside a mastered full mix, the presets themselves are inaudible. Buy from stores that let you hear the patch dry.
Velocity and note response. Run a bass patch high and low, soft and hard. Anything well built remains usable across two octaves minimum.
Making presets your own
Every preset is a starting point. Five minutes of edits and it’s yours.
- Swap the wavetable on the main oscillator and leave the rest alone. Identical movement, new character. It’s the fastest legal trick in sound design.
- Change one filter setting. Take a low-pass from 24 dB to 12 dB per octave, or flip it to a bandpass, and the entire tone reshapes.
- Resample. Print the preset to audio, then chop it, pitch it, reverse it. Bass music runs on this.
- Layer. Clean sub preset plus gritty mid patch, mid cut below 120 Hz, sub cut above it. Pro low end in two moves.
- Ride the macros in the arrangement. One “drive” macro automated across the last 8 bars into a drop beats any riser sample you own.
FAQ: Serum 2 bass presets
Do Serum 1 bass presets work in Serum 2?
Yes. Serum 2 opens every Serum 1 patch and the sound doesn’t change. It doesn’t work backwards though (patches saved in Serum 2 won’t load in Serum 1), so upgrade before buying new packs. For Serum 1 owners the upgrade costs nothing.
How do I install bass presets in Serum 2?
Put the .fxp files into your Serum presets folder, in a subfolder like “Bass”, then rescan from Serum’s menu. The folder path varies by OS; I maintain a current walkthrough in how to install Serum 2 presets.
Why does my bass sound huge solo but vanish in the mix?
Nearly always a turf war with the kick. High-pass everything else, dip the bass 2–3 dB where the kick’s fundamental lives (typically 50–60 Hz), and apply sidechain or a brief volume duck on the bass at every kick hit. Check mono too: stereo subs cancel in a hurry.
Are free bass presets good enough to release music with?
Honest answer: yes. Free packs are how most producers test-drive a designer’s style, and our free patches aren’t a lower tier than the paid ones; there are simply fewer of them. Plenty of released records run a free preset with one macro nudged.
Want a bigger library to start from? Our Serum 2 free presets pack collects 250+ sounds spanning bass, keys, leads and atmospheres. Download it, find the low end your track needs, then get back to actually writing music.
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.
