When mixing bass, sidechain compression is often used to make room for kick drums, but it also affects how listeners perceive the weight and clarity of the low end. Does the timing and ratio of the sidechain influence the balance between punch and muddiness? Are there any guidelines for setting these parameters to maintain a tight bass without sacrificing its body?
How does sidechain compression affect the perception of low-frequency bass in a mix?

Yeah, I’ve noticed that a short attack (10‑20 ms) with a moderate ratio (2:1–4:1) lets the kick punch through while the bass still holds its weight, but pushing the ratio higher or using a long release tends to make the low end sound squashed and muddy. I usually match the release to the kick’s rhythm so the gain recovers before the next hit, which keeps the bass tight without losing its body. A quick trick is to sweep the threshold while the track is playing; if the bass starts to lose its weight, back off the ratio or lengthen the release.
