Eventide Tricerachorus

The Eventide TriceraChorus is a stereo chorus pedal from Eventide that pairs bucket brigade-style chorusing with the company's MicroPitch detuning, in a tri-stereo design with three chorus voices panned Left, Center and Right¹. A three-phase LFO modulates the delay times of those three voices, creating movement across a wide stereo field, and the pedal carries a dedicated momentary Swirl footswitch for flanging, phasing and Univibe-style tones¹. It is the fourth member of Eventide's dot9 pedal family, joining the Blackhole, MicroPitch and UltraTap².

Eventide describes it as a pedal for players who want the lush, studio tri-chorus sound of the late '70s and early '80s: the design is inspired by vintage chorus units of that era, including the Dytronics CS-5 Tri-Stereo Chorus³.

A tri-chorus with MicroPitch detuning

The core of the pedal is three chorus voices, each with its own depth control, plus three chorus types: Chorus, Vibrato and Chorale¹⁵. Chorale is inspired by the classic rackmount tri-chorus units of the studio world⁵. On top of the chorus sits the Detune control, which adds in Eventide's MicroPitch detuning, the pitch-doubled thickening the company is known for; its secondary function adjusts the pitch that is being detuned³.

The main controls and what they do, as laid out in MusicRadar's review³:

Several knobs carry secondary parameters: the Left dial's secondary function adds delay of up to 200ms, and Guitar World's review also notes a low- and high-cut Filter parameter for tone shaping³⁶. The three voices can be balanced with the Left, Center and Right knobs to create a wide stereo spread².

Footswitches, presets and MIDI

The TriceraChorus has two footswitches. The Active footswitch is dual-action, selectable between latching and momentary, and in Preset mode it loads one of the five presets stored onboard, navigated with five vertically arranged red LEDs¹³⁷. The Swirl footswitch is momentary and triggers psychedelic flanging, phasing and Univibe-style tones, a function that was not available on the H9 version of the algorithm or on the plugin⁵.

Preset storage goes well beyond the five onboard slots:

• Five presets on the pedal itself, plus dozens more via the Eventide Device Manager application for PC/Mac²
• 127 user presets that can be created and recalled when the pedal is hooked up over MIDI or USB³⁷
• Premier Guitar's reviewer found the five factory presets "good jumping-off points for exploring possible extremes"⁷

The rear panel Exp jack accepts an expression pedal, with any combination of parameters mappable to it, or an external single or triple Aux switch, or MIDI over TRS; the USB jack handles connection to a computer and MIDI over USB¹. MIDI over TRS also lets the pedal integrate into more complex rigs².

Power and connections

Power comes from the supplied 9V DC adaptor, with a 200mA draw³. Connections on the rear panel are a standard input, standard outputs 1 and 2, an EXP jack and USB⁶. The enclosure is described by Eventide as rugged and gig-ready¹, and the pedal is made in China³.

From H9 algorithm to dot9 pedal

The TriceraChorus algorithm began life on the Eventide H9 multi-effects platform. Eventide unveiled it at the 2020 NAMM Show as the 52nd algorithm released for the H9, alongside a limited edition black H9 Dark, with both set for February 2020 availability⁸. At launch it was free for H9 Max owners and available to other H9 and H9 Core owners as a $19.99 in-app purchase through H9 Control⁸.

The standalone pedal arrived in October 2021 as the fourth entry in the dot9 series, following the Blackhole, MicroPitch and UltraTap pedals, at a $299 RRP². MusicRadar notes that, like the other dot9 pedals, it takes an algorithm originally housed on the H9 and gives it its own enclosure with added functions such as the Swirl footswitch³⁵. For players weighing the two routes, MusicRadar has also pointed out that the fully loaded H9 Max offers all those algorithms and more for less than the price of buying three dot9 pedals⁹.

What reviewers said

Reviews were broadly positive about the sound, with the price the main reservation³⁶.

MusicRadar's review praised a "huge range of superb modulation sounds" and concluded that it is "a chorus pedal with depth and range that makes a convincing case for rediscovering the long-lost studio pro tri-chorus sounds of the '80s and bending them out of shape for new tones"; its reason to avoid was simply that "all these features will cost you"³. The same review found inspiring sounds "from vanilla chorusing to other more extreme sounds," and noted that "with a real sense of dimension and movement, it offers a lovely wash of enriched sound with as much warble and pulse as you need," with Swirl adding "a phasey layer like a second effect"³. Gearnews found the pedal easy to use and not overly complex².

In Barry Rudolph's independent review for Music Connection's "New Toys," his guitar player took to it immediately: "My guitar player immediately started playing Jimi Hendrix songs as soon as he heard the sound of the TriceraChorus"¹⁰.

On price, the figures vary by date and source: $299 RRP at the 2021 launch², $249 street in a February 2024 Premier Guitar roundup¹¹, and $279 (with a UK price of £249) as of January 2026⁴.
