Learning how to mix kick and bass together is the difference between a low end that thumps and one that turns to mud. The two sit in the same frequency range, so the goal is to give each its own space using EQ, sidechain compression, careful level balance and a mono low end. Here is the practical approach.
Quick answer
- Decide which element owns the sub (usually one or the other, not both).
- Use EQ to carve complementary spaces for kick and bass.
- Use sidechain compression so the bass ducks slightly when the kick hits.
- Keep the low end mono and balance levels in context.
Why kick and bass fight
The kick drum and the bass instrument both live in the low frequencies, often overlapping heavily below 150 Hz. When two sources compete for the same space, the result is a boomy, undefined low end that loses punch. The fix is to make sure that at any given moment, one element is doing the work in each part of the low frequency range. Before you start, get your levels sensible with our guide to gain staging.
Step 1: Decide who owns the sub
The deepest frequencies (roughly 30–60 Hz) sound best when one element dominates them. In most modern and electronic music, the bass owns the sub and the kick provides the punch a little higher up. In rock, the kick often owns the low thump. Pick one, and shape the other to step back in that region.
Step 2: Carve complementary EQ
Use EQ to create a give-and-take relationship. For the classic approach:
- Find the kick’s main punch (often around 60–100 Hz) and the bass’s body (often a bit higher or lower).
- Boost the kick gently where it punches, then cut the bass slightly in that same region.
- Do the reverse where the bass’s fundamental lives, dipping the kick there.
- High-pass anything that does not need sub energy to clear room.
Small moves (2–4 dB) usually do the job. For the underlying technique, see our EQ and compression fundamentals.
Step 3: Sidechain the bass to the kick
Sidechain compression makes the bass duck briefly each time the kick hits, so the kick punches through cleanly. Put a compressor on the bass and trigger it from the kick. Set a fast attack and a release timed to the groove, and aim for a couple of decibels of ducking — enough to clear space without an obvious pumping effect (unless pumping is the style, as in some EDM). This is one of the most effective tricks for tight low end.
Step 4: Keep the low end mono
Bass energy spread across the stereo field can cause phase problems and weaken the centre. Use a utility or mono-maker plugin to fold everything below roughly 120 Hz to mono. This keeps the kick and bass solid and translates better on club systems and small speakers alike. Check it on accurate monitoring — see monitors vs headphones for mixing.
Step 5: Balance and check translation
Set levels in the context of the full mix, not solo. Reference a commercial track in the same genre at matched loudness. Check the balance on different systems — earbuds, a phone speaker, your monitors — because the low end is where mixes most often fall apart on smaller playback. For the bigger picture, our beginner’s mixing guide and the mixing and mastering hub have more.
Frequently asked questions
Should the kick or the bass be louder?
It depends on the genre, but they should feel balanced rather than competing. A common starting point is to set the kick first, then bring the bass up until they lock together rhythmically without either disappearing.
Do I always need to sidechain the bass to the kick?
No, but it helps in dense or bass-heavy genres. If your EQ carving already gives the kick room to punch through, light or no sidechain may be enough. Use it when the kick still gets buried.
Why is my low end muddy even after EQ?
Usually the kick and bass still overlap in the sub, the low end is too wide (not mono), or there is too much energy below 60 Hz from other tracks. Decide which element owns the sub, fold the lows to mono, and high-pass everything that does not need bass.
