The Electro-Harmonix MicroSynth XO is a guitar pedal that creates fat analog synth sounds like those heard on classic recordings by some of the finest musicians in the world. From the classic vintage sounds of the great early Moog synthesizer to custom creations, the MicroSynth effects pedal delivers. Its compact 10-slider layout lets the sonically adventurous guitarist dial in a virtually limitless array of analog synthesizer sounds, from percussive stabs to backward-sounding bowed effects.
