Title: Advanced reverb and sub bass ducking tricks (Beginner)

Alright, welcome in. Today we’re doing something that sounds advanced, but I’m going to walk you through it like a beginner lesson: how to get huge, atmospheric reverb in drum and bass without washing out your drop, and how to keep your sub tight by ducking it cleanly under the kick.

The core idea is simple. In DnB you want two things at once:
One, big space. Long tails, vibe, width, mood.
Two, a confident, stable low end. The sub should feel like it’s glued to the track, not smeared by reverb, not fighting the kick, and not wobbling when you switch to mono.

So we’re going to build a small system in Ableton Live using mostly stock devices:
A dedicated reverb return that’s filtered, controlled, and ducked.
A clean sub patch that’s easy to mix.
And sidechain ducking that’s tuned for groove, not just big gain reduction numbers.

Let’s set up the session first.

Set your tempo to 174 BPM. Anywhere from about 170 to 176 is fine, but 174 is a nice center point.

Create a few tracks:
A drums track, or a Drum Rack if that’s how you work.
A sub track.
An optional mid bass track, like a reese or growl layer.
And optionally pads or atmos, if you want something to feed the reverb later.

Now make a return track. Return A. Rename it “DnB Verb”.

Quick arrangement suggestion while we’re here, because these techniques really shine with phrasing.
Think in 16-bar blocks: 16 bar intro, 16 bar drop, then 16 bars variation.
We’re going to automate things later so the space feels musical every 8 or 16 bars instead of being stuck on one setting.

Cool. Now, let’s build the “DnB Verb” return properly.

On Return A, first device is EQ Eight. This is your pre-reverb cleanup. And this matters a lot because whatever you feed into reverb becomes fog, especially in the low end.

Enable a high-pass filter. Make it a steep one, like 24 dB per octave.
Set the frequency somewhere around 200 to 350 Hz. Start around 250 as a default.
What you’re doing is saying: reverb can be wide and long, but it doesn’t get to own the sub region.

If the reverb ends up harsh later, we’ll come back and dip a little around 2 to 4 kHz, maybe minus 2 to minus 4 dB. But don’t overdo it yet. Just know it’s there.

Next device: Hybrid Reverb. This is your main space.

Set it up as a blend: convolution plus algorithm. That combo is great because convolution can give you a realistic “room” feeling, and the algorithmic side can give you that lush tail that feels expensive.

Set decay somewhere between 1.8 and 3.5 seconds. Longer isn’t automatically better. In DnB, long tails are common, but only if they’re controlled.

Pre-delay: set it to about 15 to 35 milliseconds.
And here’s the teacher trick: pre-delay is basically depth control.
If your snare is losing impact, try increasing pre-delay slightly before you shorten the decay.
More pre-delay means the snare transients hit first, and the reverb blooms behind it. That’s how you get “big” without “blurry.”

Dry/Wet should be 100 percent because this is a return.

For a starting vibe, pick a darker room on the convolution side, like a dark room or small room.
Then choose plate or hall on the algorithm side with a moderate decay.
And if the highs get fizzy, increase damping. Damping is your “stop the hiss” knob.

Now, after the reverb, add a Compressor. This is where the control comes from.
Turn on Sidechain.
For Audio From, ideally choose your snare track. If you don’t have a separate snare track, use the drum bus. Snare is usually the classic DnB trigger because the backbeat needs to stay crisp on 2 and 4.

Set ratio around 4 to 1.
Attack 1 to 5 milliseconds.
Release around 120 to 250 milliseconds.

Then lower the threshold until you see about 3 to 8 dB of gain reduction on snare hits.

And I want you to focus on something important: sidechain timing is the whole game, not just the amount.
Stop staring at “how many dB.” Listen to when the reverb comes back.
You want the reverb to get pushed down on the snare hit, and then bloom back in the gap after it.
If it pumps too fast and sounds like it’s flapping, increase the release.
If it takes forever to come back and the whole drop feels smaller, shorten the release.

Set a soft-ish knee, like 3 to 6 dB, just to make it smoother.

Optional but useful: add Utility at the end of the return.
If your reverb is too wide and messy, pull width down to around 70 to 90 percent.
If it feels too narrow, you can push it up a little, but be careful. Too wide can cause phase weirdness and mono problems.

Alright. Now we send drums to the reverb the DnB way.

This is where beginners usually mess up: they send everything into a big reverb and wonder why the drop turns into soup.
In DnB, it’s often snare-focused reverb. The snare gives you the sense of space. The kick stays punchy and dry.

On your snare channel, raise Send A to taste. Start around minus 18 to minus 12 dB.
On hats and tops, either no send or very light. Start around minus infinity to minus 24 dB.
On the kick, usually no send. Keep it dry.

If you’re doing jungle or break-based stuff, you can send a tiny amount of the break for glue. But keep it subtle, and trust the ducking to keep it out of the way.

Now let’s build the sub.

On the Sub track, load Operator.
Oscillator A: sine wave.
If you need just a bit more audibility, you can blend in a tiny bit of triangle, but keep it clean. The goal is not a mid bass. It’s a foundation.

Set the amp envelope.
Attack basically zero to 5 milliseconds.
Release around 50 to 120 milliseconds to avoid clicks and to keep it from sounding chopped.
And one more thing most people don’t talk about: sub note length matters as much as compression.
If your MIDI notes overlap too much, the sub will smear, and the compressor has to work harder. For rollers, tighten the note ends slightly so each note has a clear boundary, but keep a little release so it’s smooth.

Now add a Saturator, but be gentle.
Drive 1 to 3 dB.
Soft Clip on.
Then match the output.
This is not to make it crunchy. It’s to generate a touch of harmonic content so the sub reads on smaller speakers without you cranking the volume.

Then add EQ Eight for housekeeping.
If this is a true sub, low-pass around 120 to 180 Hz.
If it rings or has a weird note resonance, use a narrow cut, but only if you actually hear a problem.

Now we do the classic move: duck the sub from the kick.

Put a Compressor on the Sub track.
Enable Sidechain.
Audio From: Kick.

Ratio 4 to 1 is a great start. If you want more aggressive ducking, go 6 to 1.
Attack fast. 0.1 to 3 milliseconds. The point is: get out of the kick’s way instantly.
Release: 60 to 140 milliseconds. This is the groove knob.

Lower the threshold until you get about 2 to 6 dB of gain reduction per kick.

And again: don’t mix with your eyes.
If your release is too short, you’ll hear a fluttering, like the low end is chattering.
If your release is too long, the sub disappears and your drop loses weight.
You want the sub to return just after the kick transient, but fast enough that the bassline still feels like it’s rolling forward.

A good workflow here: loop two bars of your drop, and adjust release while you focus on the “push” right after each kick.

Now we’re going to level up with the “advanced but clean” trick: duck only the low end of the reverb.

Because here’s the problem. Even with that high-pass before the reverb, you can still get low-frequency buildup in the tail, or low-mids that feel like a blanket over your drop. And if you keep cutting more and more, the reverb gets thin. We don’t want thin. We want huge, but disciplined.

So on Return A, after Hybrid Reverb, add Multiband Dynamics.

Set the low band so it covers up to around 150 to 250 Hz. Start around 200.
Mid band from there up to around 4 kHz.
High above that.

Quick check: solo the low band just for a second to confirm it’s mostly rumble and low body, then unsolo. We’re not trying to hear “music” in the low band, we’re trying to control mud.

In the low band, enable compression.
Ratio 2 to 1 up to 4 to 1.
Attack 5 to 15 milliseconds.
Release 120 to 300 milliseconds.
Lower the threshold until you see about 2 to 6 dB reduction when the drums hit.

Now, you have two ways to use this.

Simple option: keep your sidechain compressor that ducks the whole reverb, and use Multiband Dynamics mainly as low-end cleanup. This already sounds dramatically more professional than just “one big reverb.”

More advanced option: split the return into two parallel chains so you can duck lows and highs differently.

Here’s how.
Drop an Audio Effect Rack on Return A.
Create two chains.

Chain one: “Low Verb”.
Put an EQ Eight first, low-pass around 250 Hz so it’s only low reverb content.
Then add a Compressor and sidechain it from the kick or snare, depending on what’s causing the mud. Often kick is a great trigger for low reverb ducking.

Chain two: “High Verb”.
Put EQ Eight high-pass around 250 Hz.
And either no ducking here, or lighter ducking from the snare.

This is one of those pro tricks that makes the reverb feel massive because the high tail can float, while the low end stays clean and punchy.

Next advanced trick, if you’re using a mid bass like a reese: duck the mid bass from the snare.

Why? Because mid bass often masks the snare body around 180 to 250 Hz, and it can also fight the crack presence around 1 to 3 kHz.
So you can keep your bass aggressive but still let the snare be the boss.

On the Bass Mid track, add a Compressor.
Sidechain from the snare.
Ratio 2 to 1 up to 4 to 1.
Attack 5 to 15 milliseconds so a bit of bass transient can still poke through.
Release 80 to 180 milliseconds.
Aim for just 1 to 3 dB of reduction on snare hits. Subtle. But it makes space.

Now, let’s make all of this feel musical with arrangement moves.

First, automate the snare reverb send.
In busy sections, lower it a bit so your drums stay tight.
At phrase endings, like bar 8 or bar 16, raise it for drama.

A classic move is a reverb throw.
On the last snare of a phrase, crank the send just for that one hit, then bring it back down immediately after.
Big moment, no mess.

Even more controlled: right after that throw, automate the return’s high-pass up for half a bar. For example, if your return HP is at 250, push it up to 500 just briefly. The throw sounds huge, but the low-end fog gets cleaned before the next bar lands.

Another pro contrast trick: dry first four bars of the drop, wetter later.
Bars 1 to 4: tighter reverb, stronger ducking.
Bars 5 to 16: slightly longer decay or a touch more send.
It feels like the drop grows without you adding new sounds.

Now, a few common mistakes to avoid.

Don’t put reverb directly on the snare channel as an insert if you want serious control. Use a return so you can EQ it, duck it, and automate it cleanly.

Don’t skip the high-pass before the reverb. If low end feeds the reverb, you get a foggy drop.

Don’t over-duck the sub. If the sub vanishes after every kick, your track loses weight. Keep it usually in that 2 to 6 dB gain reduction range.

Don’t ignore release times. Release sets the groove. Wrong release is why mixes “breathe” awkwardly.

And reverb on the kick is almost always a bad idea in DnB. It kills punch and messes with the low-end clarity.

Now, extra coach notes that will save you time.

Use a ghost trigger for stability.
Because if you change your kick sample, or you add fills, your sidechain behavior changes. Ghost triggers make the ducking consistent.

Make a MIDI track with a tight kick or click that hits exactly where you want ducking.
Route it so you don’t hear it, like “Sends Only” or just keep it silent.
Then sidechain your sub compressor from the ghost kick, and sidechain your reverb ducking from a ghost snare on 2 and 4.
Now your mix control stays consistent even while you experiment.

Also, check low end in mono early.
Put Utility on the master, map a button to Mono, and toggle it while the drop plays.
If the bottom collapses or wobbles, something besides your sub is contributing stereo low end. Often it’s reverb returns, widened bass mids, or effects.

And do loudness-matched A/B checks.
Reverb always sounds “better” when it’s louder. Pull the return fader down until the perceived loudness is similar, then decide if it’s actually improving clarity and vibe.

If you want a quick visual check for rumble, drop Spectrum after your reverb chain and watch 20 to 200 Hz. If you see a constant hill down there, you’re fighting the sub before you even start.

Optional sound design bonus, especially for beginners who can’t hear sub well on their speakers: the harmonic “Sub Top” layer.
Duplicate your sub track.
On the duplicate, high-pass around 120 to 180 Hz.
Add saturator or overdrive to generate harmonics.
Keep it quiet. This layer is translation, not weight.
Your real sub stays clean, and the track still reads on smaller speakers.

Now let’s do a mini practice exercise so you actually hear the difference.

Load or program a basic DnB pattern.
Kick on your preferred rhythm, snare on 2 and 4.

Then do three passes of eight bars each.

Pass one: no ducking. Bypass the sidechain compressor on the reverb return. Listen to how the tail competes with the drums.
Pass two: enable the snare-ducking on the reverb. Aim for 3 to 8 dB reduction. Listen for the snare getting clearer while the space stays.
Pass three: add the low-end-only control, either multiband cleanup or the split rack. Listen for how the drop suddenly feels bigger and cleaner at the same time.

Bounce those passes and A/B them.
Ask yourself: is the snare clearer?
Does the drop feel bigger without losing punch?
And is the sub more readable, especially when you toggle mono?

Let’s recap the whole lesson in plain language.

Use a reverb return, not an insert, so you can control it.
High-pass before the reverb so you don’t create low-end fog.
Duck reverb from the snare so the backbeat stays dominant.
Duck the sub from the kick so the low end pockets correctly.
And for the advanced clean trick, duck or control only the low end of the reverb so you can keep long tails without mud.
Then automate sends and decay over 8 and 16 bar phrases so it feels like music, not a static effect.

If you tell me what style you’re aiming for, like liquid rollers, jungle, neuro, or heavy minimal, I can recommend a starting decay time, a good split frequency for the reverb rack, and sidechain release times that match that specific groove.
