MXR’s M-133 Micro Amp is a very simple, very clean boost pedal with a small footprint. Like most other MXR compact pedals, it is housed in a sturdy metal chassis and is constructed using materials and practices that satisfy baseline needs for professional use. It sports only a single gain knob and one on/off foot switch. Like its cousin the Phase 90, one of the Micro Amp’s most attractive features is its ease of use. This is a pedal designed to do only one thing: amplify.

I was impressed with the Micro Amp’s sound quality. It did not noticeably color my signal’s EQ at any level, and I noticed no additional noise when the pedal was engaged. There are boost pedals on the market with more headroom than the Micro Amp, but it can supply easily enough gain for most practical applications. The Micro Amp makes it a snap to drive the front end of a tube amp; just click one switch and twist one knob, and you are in business. Because it doesn’t have its own EQ controls, the Micro Amp cannot compensate for a tube amp with a poor on-board tone stack. It does, however, function admirably as a simple boost for managing onstage volume.

As I mentioned earlier, the Micro Amp satisfies minimum durability requirements for most professional applications, but only barely. Some users may be put off by quality of the foot switch and the jacks. Also, all the external components are soldered directly to the circuit board. That being said, the Micro Amp is quite well built considering its extremely competitive price point.
