Kick and Bass

One owns the transient, the other sustain, so low end needs room rather than more level.

The problem

Kick and bass fight over the same low band, and neither wants to move. The result is loud low end with no impact and an unclear pitch.

Goal and judgement

The kick owns the transient and click; the bass owns sustain and pitch. Check whether their fundamentals overlap. Overlap is not the problem; constant masking is. If the bass disappears every time the kick hits, it needs room, not more level.

Method

Find the kick fundamental, then cut the bass 2 to 3 dB at that point with a narrow bell. Alternatively, sidechain the bass so it steps back briefly. If the kick tail is too long, shorten its envelope instead of cutting with EQ. Keep some bass harmonics so small speakers can hear the line. Return to the full section after each change and judge impact, not just the low-frequency meter.

What to listen for

Whether the kick click comes through every time; whether the bass pitch stays stable; whether both survive on a phone speaker at low volume.

Common misconceptions

That more low end means more power; that sidechain always beats EQ; that kick and bass must occupy completely separate bands.
