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.

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.

“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.
