The MXR Micro Amp+ takes a legendary boost pedal and expands its capabilities with thoughtful modern enhancements. Delivering up to +26dB of clean gain, it can add everything from a subtle lift and added presence to the extra push needed to drive an amplifier into rich, natural overdrive. Dedicated Bass and Treble controls provide greater tonal flexibility than the original design, while low-noise op amps and true bypass switching ensure clean, transparent performance at any gain setting. Compact, dependable, and exceptionally versatile, the Micro Amp+ is an inspiring tool for players looking to shape, enhance, and elevate their core tone.

The Micro Amp+ upgrades a classic boost circuit with EQ controls, low-noise op-amps, and true bypass switching to take this powerful boost box to the next level.

For more than 20 years, the MXR Micro Amp has been a staple among the world's top artists because of its ability to boost and sweeten up your guitar or bass tone and drive the front of your amp. The Micro Amp+ builds on that classic pedal with EQ controls and other upgrades that take this powerful boost box to the next level.

With its Gain knob, the Micro Amp+ allows you to dial up just as much gain as the original—up to +26dB—but with added EQ controls, you can now finely sculpt your boosted signal. For the classic Micro Amp sound, set the Bass and Treble controls to noon.

Additionally, the Micro Amp+ now comes equipped with low-noise op amps—so you don't get any extra noise at super high levels—and true bypass switching. With the sturdy housing and durable components that MXR is known for, this pedal is ready for the road.
