Modular Delay System with pro audio heritage, advanced processing and high performance signal path.

From the minds of Meris

Fractal Brains

LVX was our goal and dream from the start.  It took over 2 years in the making.  This has been our greatest feat and we’re finally here.

"But how can it dream?"

Intuitive. Endless. Deep.

LVX is a Modular Delay System which breaks the paradigm of pre-set delay types in favor of freedom and flexibility. A completely new UI and user experience has been designed from the ground up to make LVX immediately intuitive to navigate. The architecture of LVX allows ultimate creative freedom to design a custom delay. The pedal features discrete processing elements and control signal modifiers that can be connected as desired for nearly infinite flexibility in crafting custom sounds.

Terry Burton


The LVX is the delay system I’ve been dreaming of for a long, long time. I wanted something that broke the paradigm of pre-baked delay types in favor of modularity and freedom.

WINNER of Future Music GEAR OF THE YEAR 2022 AWARD for Best Guitar Pedal.

The Meris LVX came out of our long-term review with flying colors and left our staffers in awe of what Angelo Mazzocco, Terry Burton and Jinna Kim were able to accomplish.

“The LVX has the power to realize your delay dreams.”

Considering the breadth and abilities of the LVX, we had three different reviewers spend a month each with the pedal to provide a balanced and objective review. Our reviewers consisted of a guitarist, a keyboardist and a sound designer. Even though each one came to the LVX with a different perspective, they all came away impressed.

The LVX harnesses everything you didn’t realise you were missing, and allows us to create finished, studio recording quality delays from our pedal board.

Only a company like Meris, with its unique founders, could create a product like the LVX, a delay pedal power house that’s solving every delay issue you’ve ever had while allowing you to push your tone into new and uncharted territory.

The LVX’s approachability and intuitive operation make it an appealing instrument for any artist that likes to move fast and intuitively—and doesn’t mind ending up at unexpected destinations.

The sounds it produces range from colorful, classic electric guitar effects to contemporary, large-scale, and filmic stereo reverbs and delays. It’s elaborate in a way that will satisfy the probing methods of game and film sound designers, synthesists, and other insatiably questing weirdos. Best of all is that the LVX makes investigating those complexities a simple, intuitive pleasure.

The most advanced delay pedal ever built, the LVX produces sonic landscapes that simply must be heard to be believed.

While one could use the Meris LVX as a straightforward delay unit, that would be like driving a Bugatti Chiron on half-mile errands and never exceeding 20mph.

A beautiful‑sounding, wonderfully versatile delay that can cover all bases and is mercifully easy to use.

Years of careful work must have gone into the LVX’s development, inside and out, both on the audio side and the graphical interface. The feature set is certainly impressive, but really it’s going to be the LVX’s overall sound quality and ease of control that will earn it the most praise.

Anything that gets fed into the LVX just sounds better coming out the other side, and whether you are going for an extreme change or something more subtle, this pedal will make magic.

I honestly can’t recommend the LVX enough. It’s an incredible achievement from Meris and a pedal that deserves a serious look by any musician, regardless of the instrument you plan to run through it.

The LVX has quickly become one of the most hyped delay pedals in recent years, and in just a few hours of testing it becomes apparent just why so many guitarists have fallen in love with what it can do.

The way the modules interact with each other is unlike anything I’ve played before, and it allows you to create some truly unique sounds that blur the boundaries of delay, modulation and filters in extremely inspiring ways.

The Meris LVX is exactly the delay unit I have been dreaming of.

LVX manages to perfectly walk the line between an interactive, expressive instrument expander and a reliable “set it and forget it” effect.

Perfect for the menu phobic, it’s a powerful box that’s incredibly easy to use.

Before diving in, it’s good to scroll through the LVX’s presets and experience 2,540 milliseconds of ambient deep-space echoes, many of which are mind-blowing.
