How to Sidechain Kick and 808: 4 Advanced Tricks with Compressors, Volume Shaper, Multiband Compression, and Soothe 2

Sidechaining a kick and an 808 should not be reduced to random attack and release guesses. If the low end feels weak, smeared, or inconsistent, the real issue is usually that the interaction between the kick transient and the bass sustain has not been shaped with enough intention.

The transcript behind this article lays out four distinct approaches. Each one solves the problem in a different way: traditional compressor ducking with automatic release control, waveform-based volume shaping, low-end-only multiband ducking, and frequency-selective carving with Soothe 2. The best option depends on how much precision, transparency, and tonal preservation your mix needs.

1. Use a Fast Compressor with Automatic Release Control

The first method uses a fast compressor with ARC, or automatic release control, so the kick can duck the bass more reliably than with a completely guessed fixed release. In the transcript, Waves RCompressor is used as the example because it provides fast attack and automatic release control.

The recommended setup is very fast attack, ARC enabled, and an approximately fast release setting rather than an exaggerated slow one. That last point is important. Even with automatic release engaged, the release range still matters. If you push it far out of a sensible zone, the result can stop behaving accurately.

The target gain reduction is substantial, around 15 to 20 dB in the example, because the goal is very clear visual and audible separation between the kick hit and the bass sustain. This method is simple, familiar, and fast, which makes it a solid choice when you want reliable low-end ducking without drawing detailed envelopes manually.

2. Match the Kick Waveform with Volume Shaper

The second method is one of the most precise: use Volume Shaper 3 in audio mode so the LFO retriggers from every kick, then draw the kick waveform shape and apply that inverse contour to the bass.

The transcript’s key move is to copy the shaper from the kick to the bass, trigger it with the kick through the external sidechain, and then flip the envelope vertically. That creates an exact subtractive shape that mirrors the kick contour.

This is a very controlled way to sidechain because you are not depending on detector behavior or compressor ballistics. You are literally designing how the bass moves out of the way and returns. That is why this method often feels tighter, more repeatable, and more visually intuitive. The transcript also notes that Jaycen Joshua manually draws 808 automation when kick and 808 hit together, which reinforces the idea that detailed envelope shaping can outperform generic compression in many modern mixes.

3. Duck Only the Low End with a Multiband Compressor

The third approach uses a multiband compressor so only the low-frequency region gets reduced when the kick hits. In the transcript, Waves C6 is used with very fast attack, around 30 ms release, external sidechain, and Automatic Release Control enabled.

Again, the gain reduction target is aggressive, around 15 to 20 dB, but only in the low band. That is the key advantage. Instead of ducking the entire bass tone, you remove energy only where the kick and 808 collide most.

This can preserve more character in the upper bass harmonics and keep the bass feeling present while still making room for the kick. The transcript also gives an important caution: in trap-oriented productions, other methods may be better because the kick and 808 can interact in higher-frequency ranges too, not just the sub area.

4. Use Soothe 2 to Carve the Exact Conflicting Frequencies

The fourth technique uses Soothe 2 with the kick routed into it as a sidechain so the plugin carves the exact frequencies in the bass that conflict with the kick. The example aims for around 10 to 15 dB of gain reduction.

This is a more frequency-selective approach than simple broadband ducking. Instead of lowering the bass as one block, Soothe 2 can react to the actual resonant and masking areas. That can feel more transparent, especially when the low end is dense but you still want the bass to feel large and stable.

This is one reason many top mixers like spectral or resonance-sensitive sidechain strategies: they solve the masking problem while interfering less with the musical tone of the source.

Which Sidechain Method Should You Choose?

If you want speed and familiarity, use a compressor with ARC. If you want the most sculpted and deterministic response, use Volume Shaper. If you only want to duck the sub region, use a multiband compressor. If you want the most frequency-aware approach, use Soothe 2.

In practice, the best method depends on the sound design of the kick and 808. A short punchy kick with a sustained pure sub 808 may respond beautifully to envelope shaping, while a more complex bass texture may benefit from multiband or spectral carving. The point is not that one tool always wins. The point is to choose the method that solves the exact collision in your arrangement.

Practical Workflow Summary

1. Use a fast sidechain compressor with ARC when you want a quick, reliable ducking setup.
2. Use Volume Shaper when you want the bass envelope to mirror the kick waveform more exactly.
3. Use a multiband compressor when only the low end should duck and the rest of the bass should stay stable.
4. Use Soothe 2 when you want the bass to lose only the exact masking frequencies triggered by the kick.
5. Judge the method by punch, low-end clarity, and how naturally the bass recovers after each kick hit.

Frequently Asked Questions

Why not just use one fixed compressor release setting for every song?

Because the correct recovery time depends on tempo, groove, kick length, and bass sustain. A fixed release that works on one track can smear the low end or weaken the groove on another.

Why can Volume Shaper feel tighter than compression sidechain?

Because the response is explicitly drawn. You are not waiting for a compressor detector to decide how fast to react. That gives you more predictable transient clearance and recovery timing.

Why might multiband sidechain be risky in trap?

Because the 808 and kick may interact in upper harmonics as well as the sub band. If you only duck the low end, some of the perceptual masking or tonal collision can still remain higher up.

What makes Soothe 2 different from just ducking the bass volume?

Soothe 2 can reduce the most conflicting frequencies selectively instead of lowering the entire bass signal. That can preserve weight and tone better while still making room for the kick.

Should I always aim for 15 to 20 dB of gain reduction?

Not always. Those values work as aggressive demonstration targets in the transcript, but the right amount depends on the sound and arrangement. Use only as much reduction as needed to create clear separation without making the bass feel unnaturally chopped.
