With its simple operation and stellar analog tonethe MXR Micro Chorus joins the ranks of MXR Classics such as the Phase 90, Dyna Comp and Micro Amp. This 80's reissue delivers a stunning range of rich chorus textures, from sparkly watery shimmers to intense rotating speaker simulation with a twist of the Rate control. The Micro Chorus is designed with old-school bucket brigade technology for warm analog tone and features true bypass for pure guitar tone when the pedal is off. Its road-worthy hardware and components are housed in a space saving Phase 90 sized box. Power: Dunlop ECB003 AC Adapter or Single 9 volt battery
