MXR · pedal
The MXR M233 Micro Amp+ updates the long-running Micro Amp clean boost with a two-band EQ, low-noise op-amps and true bypass switching. It provides up to 26dB of transparent gain for driving the front end of an amp harder or lifting a solo, but where the original offered only a level control, the Micro Amp+ adds Bass and Treble controls that reviewers describe as unusually responsive -- close to an extension of the guitar's own tone controls, letting the boosted signal be warmed up or brightened rather than simply made louder. The low-noise op-amps keep it quiet even at extreme boost settings, and it sits in MXR's standard rugged enclosure. A staple among professional guitar and bass players for over two decades.
