You’ve heard how good chorus sounds on an electric, and you want some of that shimmer on your acoustic-electric. The problem is that most chorus pedals were voiced for an electric in the first place.
That mismatch matters more than you’d think. Push the wrong chorus through a piezo pickup and a crisp strum can turn to mush.
The fix is subtlety. A wet/dry blend, a usable tone sweep, and clean circuitry do far more for an acoustic than a stack of presets ever will.
We rated four pedals on tone, how transparent they stay on an acoustic, and how much control you get. The chart below lays them side by side.

Voiced for Wood, Not Wire
The L.R. Baggs Align is the only chorus here designed for acoustic pickups from the ground up, with a blend control that keeps your natural tone underneath the shimmer.
The three electric-first picks still earn their slots: the CE-2W for its analog pedigree, the M234 for value, and the M134 when you want stereo spread with real EQ.
1. L.R. Baggs Align Chorus
L.R. Baggs Align Chorus
Acoustic-voiced chorus with a blend control, dual voicings, and a wide warmth-to-radiance tone sweep.
Pros
- Chorus blend keeps your natural acoustic tone intact
- Size knob morphs between two distinct chorus voicings
- Tone sweep covers warm to bright and radiant
- True bypass preserves signal when disengaged
Cons
- Pricier than general-purpose chorus pedals
- Single-purpose design, no extra modulation modes
The Align Chorus is the only pedal here built specifically for acoustic guitar, and it shows in the controls. The Chorus knob blends the modulated signal against your unaffected tone, so you can add movement without ever losing the acoustic’s natural character, while the Size control morphs between two distinct chorus voicings.
A wide Tone sweep takes you from warm and rounded to bright and radiant, which lets you match the pedal to a dark mahogany dreadnought or a snappy piezo-equipped cutaway. With a true-bypass footswitch and a clean volume control, it stays out of the way until you want it, making it the easiest recommendation for anyone running an acoustic-electric guitar.
2. BOSS CE-2W Waza Craft Chorus
BOSS CE-2W Waza Craft Chorus
Premium all-analog Waza Craft chorus that faithfully reproduces the legendary CE-2 and CE-1 voices.
Pros
- All-analog bucket-brigade circuitry for lush, liquid tone
- Recreates both the classic CE-2 and CE-1 chorus voices
- Rate and Depth knobs fine-tune both pedal modes
- Made in Japan with a 5-year warranty
Cons
- Premium price for a single effect
- Voiced for electric, so dial back depth on acoustic
The BOSS CE-2W is a premium Waza Craft pedal that faithfully reproduces two of the most revered chorus voices ever made, the CE-2 and the original CE-1. It runs on all-analog bucket-brigade circuitry, which is exactly the kind of liquid, three-dimensional modulation that sounds expensive on a fingerpicked acoustic part.
Rate and Depth knobs let you fine-tune the effect in both pedal modes, so you can keep things gentle on an acoustic and push into lush, swirling territory when you switch to electric. It’s made in Japan and backed by a 5-year warranty, and for more BOSS background there’s a good Boss super chorus vs chorus ensemble comparison worth reading.
3. MXR M234 Analog Chorus
MXR M234 Analog Chorus
All-analog bucket-brigade chorus that delivers classically lush, liquid textures with simple, effective controls.
Pros
- All-analog bucket-brigade circuitry for warm modulation
- Creates classically lush, liquid chorus textures
- Low and high frequency controls shape the wet signal
- Trusted MXR build at a friendly price
Cons
- No stereo output on this model
- Not specifically voiced for acoustic instruments
The MXR M234 is the value pick of the group, delivering genuine all-analog bucket-brigade tone at a price well below the boutique options. It specializes in classically lush, liquid chorus textures, and the simple control set means you can dial in a flattering acoustic shimmer in seconds.
On top of the standard rate and depth, it adds low and high frequency controls so you can EQ the wet signal and keep the chorus from clouding your acoustic’s high end. For a deeper look at how it stacks up in the lineup, see our analog chorus or micro chorus breakdown.
4. MXR M134 Stereo Chorus
MXR M134 Stereo Chorus
Stereo analog chorus with musical Rate and Width controls plus dedicated bass and treble EQ shaping.
Pros
- Stereo outputs create a huge, wide tonal spread
- Bass and treble controls EQ the chorus voice directly
- Musically voiced Rate and Width controls
- Analog signal path for organic modulation
Cons
- Larger and pricier than mono chorus pedals
- Stereo benefits need two amps or a stereo rig
The MXR M134 Stereo Chorus is the most ambitious pedal here, built around stereo outputs that throw a huge, wide tonal spread when you run it into two amps or a stereo interface. For studio acoustic work, that width can sound genuinely lush and immersive.
It pairs musically voiced Rate and Width controls with dedicated bass and treble knobs that EQ the chorus voice itself, giving you precise command over how the effect sits against the dry signal. It’s larger and pricier than a simple mono box, and you only unlock its best trick with a stereo setup, which is why it lands at the bottom of an otherwise strong list.
Final Thoughts
For acoustic guitar specifically, the L.R. Baggs Align Chorus is the clear winner.
Its blend control and acoustic-tuned voicing let you add shimmer and depth without sacrificing the natural detail that makes an acoustic sound like an acoustic, and that’s exactly the balance most players are chasing.
If you’re also plugging into an electric rig, the BOSS CE-2W earns its premium with two legendary analog voices and tone that flatters anything you put through it. The MXR M234, meanwhile, is the smart budget call, offering real analog warmth and EQ control for a fraction of the boutique price.
Whichever you choose, this list works just as well for classical guitars and electric guitars, and it pairs naturally with the rest of your pedalboard setup.
