The Lizard’s Mouth is predominantly a low-med gain drive and clean boost with the ability to get into harsh fuzz territory when you have all the knobs cranked.
HI – The guitarist/synth setting. The circuit follows it’s original and intended path.
LO – The bass player setting. High frequencies rolled off with a slight boost to mids and lows.
1 – Symmetrical clipping. The clipping waveform is even and equal on both sides, providing an evenly smooth overdrive/mild distortion.
2 – 2dB diode boost. Recommended to be used when using the pedal as a clean boost, with the gain turned down.
3 – Asymmetrical clipping. The clipping waveform is uneven, providing slightly harsher overdrive tones, and a tad of volume compared to symmetrical.
