How to Mix 808 and Kick So Both Hit (Without Mud)

The short answer: the kick and 808 fight because they share the same low frequencies at the same moment. Fix it in this order: tune the 808 to the song's key, decide which one owns the deep sub (usually the 808) and let the kick own the punch and click, stop them hitting at full level together (sidechain the 808 from the kick, shorten the kick, or program them apart), saturate the 808 so it's audible on phones, and keep everything below about 100 Hz in mono. Most "muddy low end" problems are arrangement and tuning problems before they're EQ problems.

I've mixed low end for my own releases (Sony, Universal, Ultra, Dim Mak, 50M+ streams), and the kick-and-bass relationship is where most mixes are won or lost.

Who owns what

Pick one owner for the sub. If both have huge sub energy at the same instant, they add up into mud and eat all your headroom.

The steps

1. Tune the 808 to the key. An out-of-tune 808 clashes with the whole song and makes the low end feel wrong no matter how you EQ it. Find the song's key and set the 808's root note to match. For reference, common 808 notes: F ≈ 43.7 Hz, G ≈ 49 Hz, A = 55 Hz. Glides should land on notes in the key too.

2. Let the kick be short, the 808 be long. A kick with a short tail punches and gets out of the way; the 808 sustains the note. If your kick has a long boomy tail, shorten it or pick a tighter sample.

3. Stop the collision. Three ways, from most transparent to most obvious:

• Program around it: start the 808 slightly after the kick, or avoid landing both on the same hit when the 808 is long.
• Sidechain the 808 from the kick: a compressor on the 808 triggered by the kick, fast attack, short release (around 30 to 100 ms), 3 to 6 dB of ducking. The kick punches through, then the 808 swells back. Sidechain compression explained.
• Layer as one sound: some producers blend the kick and 808 start into a single hit and treat them as one instrument.

4. Saturate the 808. Phone speakers can't play 40 Hz. Saturation adds harmonics higher up that phones can reproduce, so the 808 "appears" on small speakers without turning the sub up. Try the free saturation plugins on a parallel bus and blend to taste.

5. Mono the low end. Keep the kick, the 808, and everything below about 100 Hz centered. Stereo sub loses power and can cancel on club systems and phones. Stereo imaging explained.

6. Check on real systems. A spectrum analyzer helps you see buildup, but the phone speaker and a car are the real tests. If the 808 vanishes on the phone, add saturation; if the kick vanishes, boost its click (2 to 5 kHz) rather than its lows.

Mistakes that muddy the low end

1. Boosting the sub on both. One owner, one boost.
2. Fixing a tuning problem with EQ. Retune the 808 instead.
3. Mixing the low end on small speakers only, or only at loud volumes. Check quiet, on headphones you know, and against a reference.
4. Limiting the master to hear it "hit". That hides the problem. Get the balance right first; loudness comes later.

Quick answers

How do I stop my 808 and kick from clashing? Tune the 808 to the key, pick one to own the sub, sidechain the 808 from the kick (or program them so they don't hit together), and keep the low end mono.

Should the 808 or the kick be louder? Neither universally. The kick should punch clearly on its hit and the 808 should carry the sustained low end. Balance them so neither disappears on a phone or overpowers on a big system.

What frequency is an 808? Most 808 fundamentals sit between about 30 and 60 Hz, depending on the note. The harmonics above that (often boosted by saturation) are what small speakers actually play.

Do I need to sidechain my 808 to my kick? Not always, but it's the most reliable way to let both hit when they land together. Short, subtle ducking is usually enough.
