Formula B Atomo Multiboost

A Modern Approach to Clean Boost: Transparency as the Starting Point

The clean boost is an essential tool for guitarists and bassists: it's not about "changing" the sound, but about setting it at the right level at the right moment. The Atomo Multiboost takes this idea further by making Level 0 a true working base: a reference position in unity gain designed so your signal remains natural, without any coloration or unwanted compression.
From this neutral point, the Atomo becomes a step gain management system: useful if you switch between several instruments, move from a low-output pickup to a higher-output one, or change stage conditions. The goal is not to add an "effect" in the traditional sense, but to give you reproducible and immediate control over your level.

Who Benefits from the Atomo Multiboost and in What Contexts Does It Make a Difference?

The Atomo Multiboost is aimed at musicians who want a coherent and reliable pedalboard in real situations: rehearsals, concerts, mobile studios, stages with shared backline. If you play several guitars during a set (single coils then humbuckers, different tunings, backup instruments), its gain steps help you even out volumes without touching the amp or urgently compensating with the instrument's volume knob.
For bass, it's just as relevant: between a passive and an active bass, or between two basses with different output levels, maintaining a constant volume avoids fluctuations that disrupt the band's groove and the sound engineer. Finally, for styles where dynamics are key (blues, funk, pop, rock, worship, indie, post-rock), a clean boost allows you to stand out in the mix without changing your sonic signature.

Step Gain Control: Simplicity on Stage, Precision in the Signal Chain

The Atomo Multiboost is designed as a triple booster centered around 4 working levels. Level 0 serves as a reference: a flat, transparent signal corresponding to a reference output. Levels 1 to 3 allow you to adjust gain steps to compensate for weaker instruments or setups that require a bit more level.
When you need a real volume jump (solo, theme, clean passage to highlight, lead during a chorus), the Boost Mode delivers up to +25 dB of boost. Depending on where you place the pedal in your chain, its use changes: before an overdrive, it can push the gain stage harder; at the end of the chain, it serves as a clean and direct volume boost. In all cases, the philosophy remains the same: control the level without sacrificing tone.
Its compact and robust format is designed for the stage: you activate it, choose the level, and play. It's exactly the kind of tool that reduces live stress because it makes your transitions more predictable and your balance more stable.

Sound Signature

The Atomo Multiboost's signature is transparency. Level 0 is designed as a balance point: what you send in is what you get out, with intact dynamic feel. When playing with a pick, the attack remains precise; in fingerstyle, right-hand nuances and velocity variations retain their detail. The benefit is being able to increase level without the sound feeling artificial or "flattened."
In boost, the level increase can serve as a musical lever: pushing an amp already on the edge, thickening a rhythm without changing drive pedals, or simply cutting through the band for a key passage. And because the logic is based on steps, you can quickly recall your settings from one gig to another, even when the stage, backline, or acoustics change.
