The MXR Custom Shop has combined the Micro Amp's famed boosting and tone-sweetening capabilities 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. The Micro Amp+ also features true bypass.
