The 1980s were a decade of big hair, big amps, and big guitar tones. But while those stacks of cabinets certainly made things louder, behind-the-scenes rackmount chorus and in particular, the tri-stereo chorus units available under various names such as Dyno-My-Piano, Dynotronics, and Songbird, did a lot to make ’80s guitar sound bigger still. Once these rackmount units reached the rigs of guitarists such as Michael Landau and Steve Lukather, pop radio didn’t stand a chance.
After a period of relentless ubiquity, heavily chorused guitar tones went the way of Aqua Net. But chorus made a comeback, and even rare rackmount versions of the effect have been distilled into pedal form. Eventide does a swell job cramming complicated effects into compact stomps. This time around, they’ve fit the giant tones and deep functionality of rackmount tri-stereo chorus into the pedalboard-friendly TriceraChorus.

Is Three Better Than One?
Anyone who’s ever used a stereo chorus effect knows the depth and dimension it can add to a guitar tone. A tri-stereo chorus takes that idea and runs with it—creating three separate chorus signals and placing them across the stereo field—left, center, and right. The result is just as vast as you’d hope, evoking big-stadium vibes even with a pair of small combos.
Like the other pedals in Eventide's dot9 series, the TriceraChorus' dual-function knobs offer a wide range of control. On the TriceraChorus, users can use them to choose between three effect modes (chorus, vibrato, and chorale), tweak rate/rate envelope, detune amount and pitch, left/center/right levels, delay time, and filter settings. The complex nature of the pedal’s capabilities means specific settings are easy to forget, and first-time users face a bit of a learning curve. But the five factory presets are good jumping-off points for exploring possible extremes. And with the option to create 127 presets of your own you can create and recall many simple or radical formulas to suit your musical moment.
By cranking up the rate and detune past noon and playing around with a little micro-pitch shifting to taste, it was easy to evoke the Mike Stern-playing-with-Miles tones of my dreams.
Tracing The History of Chorus
In some ways, the TriceraChorus enables users to be tone archeologists and trace the history of the chorus effect to its early days. At its simplest settings, the TriceraChorus offers bucket brigade-inspired tones that evoke the sound of those ’70s stomps. And in chorus mode, with the rate at slow-to-moderate settings and the detune below noonish, the pedal offers warm gooey delights. Kick on the swirl switch and you unlock even warmer phase- and flange-style modulation. If it’s subtle sounds you seek, dialing back one or two of the three chorus level settings offers more vintage-variety sounds. On the other side of the coin, keeping the swirl engaged and switching into vibrato mode at high rate and detune settings creates worlds of weirdness.
When it’s time to lean into ’80s vibes, you’ll want all three chorus levels to be audible. I found the most hi-fi tones in chorale mode with the swirl function off. Here, tight, single-note riffs and leads sing, especially with a touch of overdrive in front of the pedal. By cranking up the rate and detune past noon and adding a little micro-pitch shifting to taste, it was easy to evoke the Mike Stern-playing-with-Miles tones of my dreams. Cranking the delay knob can deliver the pedal’s most arena-ready tones and I had a blast faking my way through everything from Alex Lifeson-style suspensions to “Purple Rain.” Whatever the settings, with all three chorus voices activated, the TriceraChorus adds a lush sparkle to clean tones and buffs out the rough edges of distorted tones to create ’80s radio-ready majesty.
The Verdict
Though tri-stereo chorus was immensely popular in its heyday, its potential is still underutilized. And while I’ve never played through a vintage Dynotronics unit to know how close Eventide got to the original vibes, I’ve played through enough chorus pedals to know that the TriceraChorus does something very different. If you want quintessentially ’80s sounds, this pedal will get you there instantly. If that’s not your bag, you might not need all the extra fuss. But this Eventide has plenty of sonic rewards to offer anyone who’s even a little curious about chorus exploration and wants to embiggen their tones.

Q: What was your biggest guitar discovery of 2024?
Guest Picker - Ariel Posen
A: Twenty-twenty-four was a year of discovery and re-discovery for me. I tend to come back to records and artists that I haven't listened to in a long time and get back into them with a new-found excitement. In regards to guitar discovery, at the end of 2023 I got into Paramore for the first time, specifically their last album, This is Why. I don't really listen to guitar music these days, but I'm always infatuated by the extreme detail of finely crafted guitar parts that help serve the song, and that album is full of that stuff. In terms of rediscovery, I spent a lot of time digging back into early George Harrison, Christopher Cross, and some specific Steely Dan records. Seems to be a theme there. I love all that stuff but haven't really given it time in a while; that changed this past year.
Obsession: Doechii. Watch her Tiny Desk video. She's incredible and the band is too. I get goosebumps every time I watch it, and I watch it once a day.
Reader of the Month - Jeremy Jacobs
A: I was turned on to Mk.Gee after seeing his performance on SNL and immediately fell in love with the vibe. I’m always trying to keep an ear to the ground for new, innovative guitar sounds, and his unique approach to creating guitar tones was really refreshing and inspiring. I love the blend of retro ’80s synth sounds and modern digital guitar production.
Obsession: Jim Lill’s video series on YouTube experimenting with guitar tone. He’s like the Mythbusters of the guitar community and it’s really shaking things up! He’s taking a very scientific deep dive into commonly held beliefs about what makes certain equipment “sound good” and has returned some truly shocking results. I’m thinking about guitar gear in a totally different way thanks to his work.

A: Big delays and reverbs finally got to me in 2024. Typically, I would favor a modest spring or room setting, but a few gigs this year pushed me into more ambient territory. It’s incredible how the sound of space affects your touch on the instrument. My playing has become more melodic and intentional—but I’m still not digging the shimmer vibe.
Obsession: Noel Johnston’s YouTube videos from his Creative Fundamentals class have been warping my brain. Fair warning: They do require a bit of theoretical knowledge to get the most out of them. However, his triad workouts are a great way to start to visualize different shapes all over the neck—no matter what key.
Assistant Editor - Luke Ottenhof
A: Last year, I discovered germanium. This isn’t strictly true; I’ve used germ pedals in the past, but I never connected with the transistors until I picked up the Death by Audio Germanium Filter. Now, all I want is sweet, gnarly, splatty germanium grossness on whatever I play. The problem is it doesn’t really fit with my band’s sound. I predict many arguments in 2025.
Obsession: Figuring out ways to make, share, and celebrate music outside of the too-powerful platforms that have monopolized our arts and culture. Thankfully, there are loads of people way smarter than me working with each other to build new networks and meanings for music, including some that would be musician-owned. The future is bright—if we want it!

The collection features several groundbreaking design elements, including the new Super Auditorium body style, a Fanned V-Class bracing pattern, and a long-tenon neck joint, all of which contribute to a richer, more resonant, more muscular sound. The collection also introduces two distinctive wood pairings: Honduran rosewood back and sides with a torrefied Sitka spruce top, producing exceptional harmonic richness, and figured Hawaiian koa coupled with torrefied Sitka spruce, delivering a more balanced, rounded tone.

“The harder you play, the louder the guitar gets,” says Powers. “But it naturally starts to compress the sound into a more controlled, focused tone rather than becoming mushy. Yet these guitars also respond to delicate articulation with a broadly rich voice. When you play a simple note softly, the guitar naturally amplifies it with surprising warmth and volume.”
With its unique sound and aesthetic, the Gold Label Collection sits apart from Taylor’s other premium lines, offering a guitar that combines the warmth and tonal character of traditional instruments with the playability and reliability Taylor is known for. The collection's craftsmanship extends beyond its sonic capabilities, with a fresh visual aesthetic that combines classic influences with modern artistry. The result is a guitar that will appeal to a broad range of players, offering a distinctive voice and performance that bring together the best of both old and new.
Whether for recording, live performance, or personal enjoyment, the Gold Label Collection provides musicians with a guitar that is as visually striking as it is sonically impressive.
