Product Description
The MXR Booster Mini delivers iconic tone-shaping capability in a compact, pedalboard-friendly package. Combining the celebrated sonic enhancement of the Echoplex Preamp with the renowned punch of the MXR Micro Amp, this little powerhouse offers up to +25dB of clean boost and refined tone control. Whether you want to soar above the mix, add clarity to your solos, or inject extra grit into your signal, the MXR Booster Mini is the secret sauce your pedalboard has been craving.
Legendary Boost in a Mini Pedal
Taking inspiration from two of MXR’s most esteemed pedals, the MXR Booster Mini distills decades of tone wizardry into a lightweight, space-saving enclosure. The intuitive controls let you dial in just the right amount of volume and presence, while an internal Echoplex Preamp trimpot adds a customizable layer of warmth and drive. Perfect for players who value both sound quality and pedalboard real estate, this pedal makes it easy to achieve professional-level tone anywhere you play.
Precision Tone Control
The MXR Booster Mini’s Volume knob offers up to +25dB of gain, giving you the flexibility to lift your signal for solos or simply push your amp into natural overdrive. The Tone control lets you roll off highs for a smoother, vintage-inspired character, or leave them wide open for maximum clarity and chime. Inside, the Echoplex Preamp level can be fine-tuned with a trimpot, letting you add extra grit or keep things pristine.
Space-Saving Design, Gig-Ready Reliability
Engineered for the modern gigging guitarist, the Booster Mini’s rugged mini enclosure is built to last while taking up minimal space on your board. Its simple interface means you can make adjustments on the fly, and the pedal’s high-quality circuitry ensures your sound always cuts through, whether you’re playing at home, in the studio, or live on stage.
