Essentially an octave, fuzz, and envelope filter all in one, the Electro-Harmonix Bass Micro Synth sports ten sliders for a virtually limitless array of analog synth sounds. The pedal has four voices (Guitar, Octave, Sub-Octave, and Square-Wave), each of which can be completely independent or fully mixed. Create tones ranging from the sounds of vintage Moog synths to wilder, more modern sounds with the Electro-Harmonix Bass Micro Synth pedal.
