Inspired by vintage circuits, ARC OF LIGHT Radium Overdrive delivers rich, expressive gain with exceptional touch sensitivity and a natural cleanup from your guitar’s volume control.
From low-gain texture to a more driven, harmonically rich voice, it stays open, articulate, and alive

Arc of Light is a french boutique guitar pedal brand born from a simple obsession : tone before gain, feel before volume.
Arc of Light stands for a musical, organic, and timeless approach to guitar effects. Simple circuits refined to their essence. Components chosen for character, not hype. Pedals designed as real instruments — meant to enhance an existing sound, not overwrite it.
Arc of Light pedals are designed to preserve the natural character of your guitar and amp, respond dynamically to touch and volume, move seamlessly from subtle tone enhancement to rich, alive saturation, work just as well into a clean amp as into one already pushed.
Every circuit is developed in real conditions: rehearsals, studios, stages, real amps at real volumes. Not in simulations. Not on spreadsheets.
