Creating Depth: The Best Chorus Pedal for Your Pedalboard

For years, chorus effects felt like relics of the 80s — forgotten and gathering dust alongside old VHS tapes. But lately, they’ve made a big comeback. From subtle width to bold, warbling tones, chorus has returned to the spotlight.

You’ll recognize it as this liquid texture in ‘80s pop, psychedelic riffs or even on those dreamy shoegaze tracks. It’s the classic “doubling” effect that turns a single instrument into something richer and way fuller. Now, even bedroom producers use this kind of modulation to add some shimmer and depth to their soundscapes.

So, what exactly is chorus? It’s an audio processing technique that creates a rich, shimmering sound by copying the original signal and slightly altering its time and pitch. This delayed signal is usually spaced around 15–35 milliseconds and sits just slightly off-pitch from the original source.

When you pair the dry signal with the altered signal, the "chorus" effect comes to life. It’s easy to see why chorus is such a go-to tool for achieving that "doubling" sound, especially when you start dialing up the intensity.

It’s easy to confuse chorus with its close cousin, the flanger. In fact, most people assume the guitar on The Police’s "Walking on the Moon" is chorus. (Spoiler alert: it’s actually a flanger). So, what gives?

The main difference is the delay time. Flanger keeps things close together, usually running under 20 milliseconds. Since they’re cut from the same cloth, nowadays you’ll often find chorus and flanger sharing space in the same stompbox, ready to add that extra bit of sparkle and character to your tone.

Chorus fits seamlessly into almost any part of a production. It does more than just add character; it's a simple way to expand your stereo image and add depth to your mix.

You can use chorus on your guitars, basses, synths, vocals, drums — pretty much anything you can think of.

It’s a great addition to your pedalboard, too. I love using chorus as a subtle effect on my guitars, especially with a bit of overdrive, just to give it some more weight and texture.

When using a chorus pedal in your rig, you’ll mainly focus on three controls:

• Speed: Controls the rate of the effect.
• Depth: Controls the intensity of the modulation.
• Width: Controls how wide the stereo field of the effect will be.

Depth and Speed determine how much the signal gets detuned and how quickly. You’ll generally find that slower speeds sound more natural, while higher speeds create a more exaggerated, choppy effect.

In your signal chain, try placing the chorus pedal after your overdrive and distortion pedals but before time-based effects like reverb and delay. Of course, feel free to experiment — moving things around can yield different sounds, but this is a solid starting point.

Here are a few of our handpicked favorites from the chorus department. While many modern pedals come loaded with an abundance of features and knobs, I prefer to keep things simple — fewer knobs mean less tweaking and more playing.

That said, quite a few modern chorus pedals also feature a flange effect, which is something to consider if you want to keep your sonic options open.

• Boss CE-2W Chorus Waza Craft
• JHS 3 Series Chorus
• MXR M234 Analog Chorus
• Universal Audio Astra Modulation
• Ampeg Liquifier Analog Chorus
• Walrus Audio Julia V2 Analog Chorus Vibrato

You really can’t go wrong with any of these chorus pedals, and I highly recommend testing out a handful so you can experiment and see which ones match your style best.

Chorus is the secret sauce for your guitar tone. It adds a subtle sparkle to clean sounds and beefs up your overdrive. By widening the stereo image, it provides depth and dimension without muddiness. A little goes a long way — just a touch can transform your sound. Toss some chorus into your rig; trust me your ears will thank you.
