The Meris MercuryX is the first pedal I’ve ever played that has its own glossary, found near the back of its 32-page user manual. Advertised as “a Modular Reverb System with pro audio and studio rack heritage,” the USA-made MercuryX builds on the foundation of Meris’ Mercury7 reverb unit, which was inspired, in part, by the Lexicon 224 Greek musician Vangelis used to score for Blade Runner. The Mercury7 is a richly featured and widely celebrated effect. But by comparison, the MercuryX makes it look like an abacus.
The MercuryX’s price bracket is about as high as it gets for a non-vintage effects pedal, but spend an hour with it, and you’ll realize the staggering amount of work the Meris team must have poured into it. It’s a feat of audio engineering and imagination that can take you anywhere you want to go.
Guide to the Galaxy
Though it features an almost comical amount of adjustability, the MercuryX is hardly a bother to operate in Meris’ default graphic view on the digital display. (The text view, comparatively, felt labyrinthine, if not flat-out impossible to navigate.) Three of the pedal’s seven knobs help you navigate the edit pages, where you can adjust a suite of parameters that, like the haunting reverb algorithms, feel like they never end. The 99 preset slots are divided into banks of three, which are selected and cycled via different combinations of the four footswitches. A favorites bank lets you keep your top three presets in immediate grasp. Plus, simultaneously pressing the two switches on the right will call up a tuner on the display. The MercuryX is powered by an ARM processor which helps enable its breadth of modulation options, including tremolo, chorus, vibrato, pitch shift, tape emulation, and more. Then there’s discrete filtering, compression, and preamp gain. Each of these functions is, of course, deeply tweakable, down to independent high- and low-frequency controls. The glossy deep-blue box is equipped with mono and stereo outs, expression pedal in, MIDI jacks, and USB-C for firmware updates. It’s sleek, but more importantly, it feels like resilient armor for the complex guts contained within.
Reverb of the Nerds
It’s clear that the builders at Meris are ginormous reverb nerds. The MercuryX contains eight distinct reverb algorithms. A few are ported from the Mercury7, while others are brand new. There’s every sort of reverb sound imaginable, and they’re all magnificent. You can dial in a tight, humble spring reverb, then jump to a pitch-shifting, interdimensional wormhole or a steely, dystopian fog.
And though they invite customization, the 87 Meris-made presets are each instantly cinematic and usable. The depth of these reverbs can be difficult to convey: Somehow, every single one is imaginative and stirring, suggesting different tones, voicings, picking styles, and progressions. (I could only imagine how they’d sound with a synth, bass, or vocal.) Plus, every setting in the presets can be individually tinkered with and saved, so there’s really a mind-numbing amount of flexibility here.
But that flexibility triggers some option paralysis, too. I found myself sticking to the MercuryX’s pre-programmed settings rather than trying to build my own for two reasons. There were simply too many variables to modify, and the reverb aficionados at Meris know what they’re doing. Why overcomplicate things?
The MercuryX’s only flaw might be that it occupies an awkward in-between spot in the market. Its capabilities (and price tag) eclipse many of the higher-end reverb units available, and in practice, it often feels closer to a compact floor modeler than an effect pedal. But it is just an effect pedal. Though, maybe this is a sign of things to come: The MercuryX really does lend the feeling that, at least as far as reverb is concerned, it can do everything.
The Verdict
For the right user, the MercuryX’s complexity will be a major asset. Learn how to manipulate all the processing power included here and this pedal might be a game-changer.

Galloup’s Plek tech Adam Winarski preps a Yamaha acoustic for the machine.
Presently, many certified guitar-repair specialists possess the expertise required to deliver an instrument that both sounds and plays wonderfully. The standards set by manufacturers and distributors have significantly risen, safeguarded by rigorous quality protocols to guarantee the best possible acoustic experience for customers. Additionally, lutherie training has raised the bar for critical processes, and one of the most tricky is fretwork.
Traditional fretwork once involved manual labor, with technicians utilizing sandbags or similar supports to steady the neck as they straightened it with a truss rod during the filing process. A notable advancement in this field came in the mid 1970s when Don Teeter, an author and repair expert, imposed a new method: fixing the guitar body to the bench and using blocks to maintain the neck in a playing position. This refinement was one of many in the continued quest to produce superior instruments by standardized methods.

In the late 1970s, another pivotal innovation was introduced by Dan Erlewine. He created an advanced fret jig with a specialized body-holding system and neck supports, adding another layer of precision to the repair process. During my collaboration with Dan in 1985, we developed a rotating neck jig that counterbalanced the forces of gravity, keeping the instrument in its playing orientation while adjusting the neck supports. This step represented a significant leap in establishing control and standardization of fretwork procedures in our industry. By 1986, our approach had evolved into a freestanding workstation coupled with a sophisticated hold-down mechanism and enhanced neck supports, culminating in increased accuracy, efficiency, and consistency. Over the decades, the Erlewine/Galloup rotating neck jig has become a benchmark in numerous shops, enhancing fretwork performance.
"This step represented a significant leap in establishing control and standardization of fretwork procedures in our industry."
By the 1990s, automated and computerized technologies permeated the guitar manufacturing and repair sectors. Initially applied by import companies in the mass production of guitars, the technology, although expediting processes, did not immediately achieve high execution standards. However, the tech dramatically improved over time, with computer-driven systems eventually transforming the industry. Contemporary automated production utilizing such advancements meets exceedingly high standards of precision. Some bespoke guitar manufacturers, such as Steve Andersen, were pioneers in adopting these methods, but it was companies like Taylor that established them in the modern era.
Inevitably, the progression of technology extended beyond the mere production of parts. Around 1995, German engineer Gerd Anke envisioned the integration of computer-assisted technology into enhancing instrument playability, giving rise to Plek technology, which uses computers to precisely measure and analyze the various components of a guitar, like neck relief, fret height, nut and bridge specs, and more. Nashville guitar-repair tech Joe Glaser was among the first to recognize the machine’s value, followed by San Francisco luthier Gary Brawer. When Heritage Guitar Inc. invested in a Plek machine, the guitar industry could no longer disregard the significance of this innovation.
“The machine’s scanning data confirmed that there was one nature of an ideal fret plane, done by hand or machine, and unsurprisingly, it conformed exactly to what physics predicts, not personal mojo.”
In the spring of 2022, Galloup Guitars obtained its first Plek machine. Promptly, our technician Adam Winarski paved the way for the Plek’s integration in our shop. Now, it’s a rarity for an instrument to leave our shop without having undergone Plek analysis and machining. Impressed by the results of our integration, we created “Intro to Plek” as a course for all students enrolled at the Galloup School of Lutherie, offering our students a practical introduction to this technology. We furthered this educational initiative with a comprehensive one-week intensive “Plek Certification Training Course” for both students and the public. This advanced Plek course serves those seeking to boost their knowledge base and employability in this high-precision field.
Plek is rapidly becoming an industry standard for major manufacturers and smaller shops alike. However, this does not mean that those without access to this technology cannot execute proficient fretwork. Personally, I continue to use my Erlewine/Galloup neck jig—not only out of nostalgia, but also because it remains an excellent method for delivering accurate and reliable guitars. Still, it’s undeniable that the process of fretting, fret dressing, and analytics of fretted instruments has undergone significant transformation, resulting in better sounding—and playing—guitars. And ultimately, that’s what it’s all about.
