The Fundamental Distortion is a 3-mode distortion. It covers a wide range of sounds from dark and doom through sharp cutting leads.

Gain – The Gain slider sets the amount of gain applied to your guitar signal passing through the fuzz circuit.

Tone – The Tone slider controls the frequency response of the signal after distortion. Below center boosts highs and above center cuts highs.

Volume – The Volume slider sets the overall output volume of the pedal.

Slide Switch – The slide switch allows you to change between 3 distinct flavors of the pedal. Each position has different clipping modes or tone profiles.

• Dark - Asymmetric silicon clipping with added high-frequency cut. Think dark and dynamic.
• Si - Classic silicon hard clipping diodes. Things get compressed and crunchy.
• LED - LED hard clipping diodes. A dynamic and crunchy sound.

Note: The LED clipping mode will be louder due to the nature of the LEDs, so use your volume slider to compensate!

Bypass Switch – Turns the effect on and off.

Bypass LED - Illuminated when the effect is engaged.
