How to saturate drums

Gazillion Industries ·

The drums came out of the pack spotless. Every hit sharp, every hit even, and the whole kit about as warm as a hospital hallway at 4 a.m.

Saturating drums means driving them into gentle distortion so they pick up harmonics, lose a little peak, and sound denser and more present, especially on small speakers. Put it on the kick and snare for character, on the drum bus to pull the kit together, or on a parallel copy you blend in under the clean drums. Use less than you think, watch the cymbals, and compare at matched loudness.

The short version

Kick
harmonics so the body reads on small speakers
Snare
thicker body, more crack; takes more drive
Drum bus
density and glue; watch the hats
Parallel
drive a copy hard, blend it under
Order
before or after compression; both work
Amount
until you hear it, then back off
Check
at matched loudness, on a phone too

What saturation does to a drum

Saturation adds and takes. It adds harmonics, new frequencies stacked above the ones the hit already has. And because the curve flattens as it's pushed, it takes a little off the peaks, which brings the body of each hit up toward its front edge.

The shape of the curve sets the color. Symmetric curves add mostly odd harmonics and tend to sound edgier; asymmetric curves add even harmonics too and tend to sound rounder. Either way: more to hear, less spike.

Kick

The kick has to be heard where it can't be felt. A little saturation puts harmonics above the body, where a laptop can play them. Too much and the low end goes woolly as the sub itself distorts. If that happens, saturate a copy with the lows cut out and blend it back under the clean kick.

Snare

Snares usually take more heat than kicks, because most of what makes a snare a snare lives in the mids. Drive it until the body fattens and the crack comes forward. Stop before the crack turns to paper (you'll know; it sounds like a stapler).

The drum bus

Bus saturation is a group decision. Every hit pushes the curve for everything playing at that moment, so when the kick lands, the snare and hats get driven with it. That shared push is the glue on a good day and the grit on a bad one.

A little on the whole kit pulls the hits and the room closer together. A lot turns cymbals into sandpaper on every downbeat. If the top end gets harsh, keep the hats and cymbals out of the saturated bus, or darken what goes into it. For the compression side of the bus, see drum bus compressor settings.

Parallel saturation

Keep the clean drums and add the burnt ones.

  1. Send the drums to a return track.
  2. Put the saturation on the return and push it harder than you would on the channel.
  3. High-pass the return if the kick's sub starts to smear.
  4. Blend the return in under the dry drums until the kit thickens, then pull it back a touch.

The front edge stays with the dry drums and the density comes from the return, so you can push the saturation further than an insert would allow.

Or put BEEFY on the drum bus and turn up BEEF. The demo on the page is 28 seconds.

Before or after compression?

Both orders work, and they sound different. Saturation first means the compressor reacts to peaks that are already softened, so it works less and the kit gets dense early. Saturation after means a punchy compressor setting, with its slow attack, hands the curve a sharper front edge, so every hit drives it harder. Try both and keep the one you would rather listen to.

Tape, tube or clipper?

The name on the plugin matters less than the curve and how hard you hit it. Tape-style saturation tends to soften transients and the top end. Tube-style is usually described as rounder. Clipper-style is the most aggressive on transients, which makes it the most obvious on drums. Hit any of them softly and they sound more alike than the marketing suggests.

How much

Until you hear it, then less. Saturation adds level, and louder always sounds better for a few seconds, so level-match against bypass before you judge. Then play it on a phone. If you notice the saturation before you notice the drums, back off.

If you've crushed the drums already, soft clipping explained covers the peaks, and how to make drums hit harder covers everything around them.

Questions people ask

Should I compress or saturate drums first?

Either works. Saturation first gives the compressor softer peaks to react to, so it works less. Saturation after lets a slow-attack compressor hand the saturator a sharper transient, so it bites harder. Try both on the same loop and keep the one you prefer.

Is saturation just distortion?

Yes, mild distortion. Saturation is the gentle end of the same process: the waveform bends a little, adds harmonics and softens its peaks. Push the same curve harder and people start calling it distortion.

How much saturation should I use on drums?

Enough that the drums sound thicker at matched loudness and still keep their front edge. If you notice the saturation before you notice the drums, back off.

What BEEFY does

BEEFY is our saturation and loudness plugin. Put it on the whole drum bus to pull the hits and the body closer together, or give a kick or a snare its own helping.

BEEF is the main control: more weight, density and loudness as it goes up. COOK changes the color and bite, from a rounder feel toward a brighter, more cooked edge. SOFT CLIP opens switched on and handles the initial gain staging, and LIMIT holds the output peaks instead if you prefer. For parallel saturation, run it on a return track like any other insert.

Same drums, same pack. They just don't sound like a hospital hallway anymore.
