MXR Micro Amp Pluschat_bubble_outlineFrom real comments

Opinions split between simplicity fans and those who welcome added EQ control. Someone who owns the original M133 Micro Amp says they love its single-knob simplicity and are not sure they would want to deal with three knobs on what is meant to be a boost pedal. On the other hand, another user wants to place the Plus at the end of their rig specifically to use it as an equalizer, and a third describes it as functioning more like a compressor with EQ controls rather than a plain boost, showing the extra knobs do appeal to some players seeking tone-shaping flexibility.

The pedal's IC-chip circuit sets it apart from simple transistor boost clones. One commenter who built their own boost pedal clone from scratch, based on a 2n5088 transistor pushing the signal, points out that the MXR Micro Amp Plus instead uses an IC chip for its circuit. Despite this different approach compared to a bare transistor design, they still call the MXR version 'great,' suggesting the IC-based circuit holds its own against simpler DIY builds even though the underlying philosophy is different.

Some users feel the Plus colors tone poorly and lacks real compression. Not every reaction is positive: one user calls the pedal cheap sounding, saying it takes away from tone instead of improving it and recommends saving money for something else, despite otherwise liking the MXR brand. Another user describes the Plus as feeling more like a compressor with EQ controls, but notes it does not actually include compression parameters, leaving its functional identity a bit ambiguous for those expecting either a pure boost or true compression.
