For the Fundamental Series, Walrus Audio challenged themselves 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.

The Fundamental Tremolo is a classic optical tremolo, giving you that iconic chewy movement. With 3 wave shapes to select from, you can get sounds from smooth and soothing to glitchy and crazy.

Rate – The Rate slider sets how fast or slow the LFO is oscillating.
Depth – The Depth slider controls the strength of the tremolo effect.
Volume – The Volume slider sets the overall output volume of the pedal.
Slide Switch – The slide switch allows you to change between 3 distinct oscillator waveforms: Sine, Square, and Random.
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
