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 MXR Custom Shop team has combined those features with a specially-tuned EQ section and low-noise op-amps to create the Micro Amp+.
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.
Along with these upgrades, the MXR Custom Shop team added 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.
MXR Custom Shop effects are designed for discerning players with unique and specific needs—players who know their gear inside and out and carefully consider every part of their signal chain, from guitar output to amplifier input. Likewise, the Custom Shop’s master pedal builders consider every component and circuit board layout choice with the same discretion, ensuring players with refined tastes and finely tuned ears get the tools they need for their own sonic exploration.
