For the Fundamental Series, we challenged ourselves to design a set of pedals with the tonal integrity that’s required to live on a professional’s pedalboard, but with simplified controls friendly enough for even the newest effect pedal users. Each Fundamental pedal has 3 sliders for tweaking the sound and a three-way switch for changing pedal modes. The result is a line of 8 pedals that will keep you covered from your first band practice all the way to a sold-out arena. Designed and assembled at Walrus Audio headquarters in OKC, OK.

Fundamental Distortion

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.

Input Jack - 1/4 inch cable from the instrument. 

Output Jack - 1/4 inch cable to amplifier.

9v Jack – 9-volt DC, Center Negative, 100mA min.
