Rowin Analog Chorus

The Rowin Analog Chorus is a chorus pedal made by Rowin. Chorus is a modulation effect: the pedal takes your guitar signal, delays it slightly and continually varies that delay, and mixes the moving copy back with the original. The result is a thicker, richer sound, the impression of two or more instruments playing the same part together.

The word "analog" in the name refers to how the modulation circuit is built. Analog chorus pedals use bucket-brigade delay chips to create the modulated copy, the same approach as the classic chorus designs of the late 1970s and 1980s, and makers position them against digital chorus on the character of that circuit. Voodoo Lab, whose Analog Chorus is one of the best known examples, describes the sound of its analog circuit in plain terms¹:

What it does

An analog chorus pedal sits in your signal chain like any other stompbox: guitar into the input, output to the amp. Analog Man's chorus manual puts the basic hookup simply: "Plug in guitar on right (IN) and amp on left (OUT)"². From there, the effect thickens single-note lines and chords, and at deeper settings it moves toward more pronounced modulation.

How far the effect goes depends on the controls. Most analog chorus pedals keep it to two knobs:

Voodoo Lab's Analog Chorus uses an Intensity and a Speed control, and a 2006 MusicPlayers.com review by Scott Kahn noted that the mono-only pedal keeps to just those two knobs³. The Analog Man BI-CHORUS takes a different approach: two complete sets of SPEED and DEPTH knobs, so you can set two different chorus sounds and switch between them without touching a knob⁴.

The range of sounds

Makers describe analog chorus as covering more ground than a single effect. Voodoo Lab says its pedal is "capable of a wide range of sounds from a thick analog doubling, to an uber-lush chorus, and even a Leslie rotating speaker"⁵. That range is typical of the type: at low depth the effect reads as doubling, at moderate settings as classic chorus, and at high speed and depth it approaches the sound of a rotating speaker. MXR describes its Analog Chorus as creating "classically lush, liquid textures"⁶, and NUX markets its analog chorus as a "Vintage Analog Chorus Effect"⁷.

Some pedals in this family add a voice or character switch. Pedal of the Day's 2026 review of the Enduring Audio Charming Voices Analog Chorus walked through its full control set, noting the controls that round out the pedal beyond the basic speed and depth⁸.

Where it sits among modulation pedals

Chorus is one of several modulation effects that use the same delayed-and-wobbled-signal trick at different settings. A flanger uses a shorter delay for a jet-like sweep, a phaser shifts phase rather than delay, and a vibrato modulates pitch without mixing in the dry signal. If you want to hear the effect in a fixed, switchable form rather than a knob-based pedal, the MXR Rockman X100 Analog Tone Processor's Chorus button, as Pedal of the Day described it, "will infuse every riff and lick with bucketfuls of expansive, shimmering chorus with a simple push of the Chorus button"⁹.
