With its simple operation and stellar analog tone, the MXR Micro Flanger joins the ranks of '80s reissue MXR Classics such as the Micro Chorus, Phase 90, Dyna Comp Compressor, and the Micro Amp. The M152 produces all the iconic MXR flanger sounds from the M117 in a more compact unit, with the same two controls, Speed and Regeneration, to shape your sound. The Micro Flanger is designed with old-school bucket brigade technology for warm fat analog tones and the sort of sound quality you've come to expect from MXR. It also features modern true bypass to preserve you tone when the pedal is off. It's all housed in a complact pedal board friendly enclosure.Power comes from a single 9V battery or the optional a Dunlop DC810DC brick, or MC403 Power system.
