ITS BLACK not white early version, all original. Built with the iconic MXR chassis and a single control for volume, the MXR Micro Amp is one of the earliest effects for what a booster pedal should be. Operating on all-analog circuitry, the Micro Amp works wonders placed first on a signal chain for clean, immediate decibel bumps without any EQ coloring on your tone. Whether you're playing hair metal, reggae, or blues, every pedalboard can benefit from a boost, and the vintage Micro Amp is a perfect choice.

The pedal is compatible with a range of electric instruments, including guitar, bass, piano, and clavinet, and is intended to add dynamic variation and expressive filtering to both solo and accompaniment contexts.

Tested and fully functional. It has the original warranty card and instructions, but I doubt they would honor it now in 2026.

Foam has been removed from inside the pedal.

A great early example from 1983 production.
