Spaceman effects Atlas IV Preamp Booster - Olive Drab

Discover the SPACEMAN EFFECTS Atlas IV Preamp Booster (Olive Drab) effects pedal, a remarkable evolution of the famous Atlas III that offers expanded sonic possibilities for all musicians.

Overview

The compact Atlas IV effects pedal replaces the popular Atlas III, significantly expanding your tonal options. When paired with a tube amp set to a crunch tone (edge of breakup), this pedal produces organic, expressive, and responsive overdrives that accurately capture every nuance of your playing. It’s the ideal tool for elevating your solos or enhancing the potential of other overdrive pedals.

An analog circuit for rich, natural dynamics

Featuring a 100% analog circuit built around field-effect transistors (FETs), the Atlas IV offers up to 15 dB of boost, with a wide and pleasant dynamic response. This pedal is more than just a simple volume booster; it enriches your tone with new harmonics while preserving your instrument’s fundamental character.

Innovative filters for enhanced tonal flexibility

The Atlas IV features two new filters, Thrust and Axis, for even greater sound customization:

• Thrust: boosts harmonic saturation while slightly reducing headroom. The result: brighter highs and more solid lows, with a maximum output level increased by 5 dB.


• Axis: alters the tonal balance by attenuating low frequencies and emphasizing the highs, transforming the Atlas IV into a treble booster suited to your guitar’s various pickup types.

The combination of these two features offers a wide range of tonal options, from a transparent clean boost to rich, punchy harmonic distortion.
