"The MXR Booster Mini is actually two pedals in one."

As a reviewer, there are two kinds of gear you dread writing about: volume pedals and clean boosts. A, they kind of do only one thing, and B, um, that’s about it. So, imagine my anxiety when I heard I was covering yet another clean boost. However, all apprehension was put aside when the MXR Booster Mini showed up on my desk for review, because A, it’s MXR, and B, it definitely does more than one thing—and does it extremely well.

The MXR Booster Mini is actually two pedals in one, combining the sought-after boost found in the MXR Micro Amp and the subtle gritty edge from the Echoplex Preamp, which also offers a touch of musical compression. 

The Booster Mini comes in a lightweight mini-housing and features controls for volume and tone. The volume control offers up to +25dB of boost, and the tone control is a studio-grade high-cut knob. What makes the Booster Mini useful is an internal preamp level trimpot that adds gutsy gain, which is a great way to fatten up single-coil guitars and increased drive for humbuckers.

I tend to put boost pedals after my drive pedals, and the Booster Mini works well in this capacity. Setting the internal preamp control about a quarter of the way, the Booster Mini is surprisingly loud (even at 9 o’clock on the volume) with a slicing saturation that works great for solos. The musical tone control removes high-end harshness and smoothens unwanted frequencies. Using it as a boost in front of an amp, the pedal responds with warm sustain and ballsy overdrive. It’s hard to believe MXR has packed this much firepower in a mini boost. And that’s no small wonder.
