The EHX Lizard King is a fixed-gain fuzz that is dynamically responsive. Adjustments to your instruments volume affects the amount of fuzz. Lower instrument volumes create a clear, fuzzy overdrive, while full instrument volume sends the gain over the top for ripping riff and searing solo tones. The familiar VOLUME and OCTAVE knobs control overall output and octave blend volume respectively. New to the Lizard King, the BLEND knob sets the mix between your clean and fuzz tones to create the perfect balance of fuzz while retaining your bass’s attack and low-end. The TONE knob is a low pass filter that rolls off the highs, while the SUN/SHADOW switch further enhances the tone of the octave fuzz and clean tones. SUN boosts the octave fuzz with a more driving midrange, and the clean tone accessed by the BLEND knob has more treble and bass frequencies. When the switch is set to SHADOW, the clean tone is unchanged, and fuzz tone is tighter.
