Used MXR M233 Micro Amp+ Boost Pedal

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. 

The Micro Amp+ enhances this legacy by adding EQ controls and improved features for greater tonal shaping. It offers up to +26dB of gain through its Gain knob, identical to the original, but now includes Bass and Treble adjustments to precisely tailor your boosted signal—set them to noon for the classic sound. Featuring low-noise op amps and true bypass, this pedal delivers clean boosts without added noise. Built with MXR’s durable design, it’s road-ready and reliable. This pedal is in good condition. 

This pedal can be powered by a 9-volt battery, a Dunlop ECB003 9-volt adapter, or the DC Brick™, Iso-Brick™, and Mini Iso-Brick™ power supplies (not included).
