Walrus Audio Fundamental Series Tremolo

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 three faders for tweaking the sound and a three-way switch for changing pedal modes. The result is a line of 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 Tremolo

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

Rate – The Rate slider sets how fast or slow the LFO is oscillating. A lower rate gives a gentle wavering texture, while a higher rate gives a shimmering and pulsating effect.

Depth – The Depth slider controls the strength of the tremolo effect. At a lower depth, the volume oscillations stay closer to the input for a more subtle movement. At a higher depth, the tremolo becomes more pronounced with the volume are greater.

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

Slide Switch – The slide switch allows you to change between three distinct oscillator waveforms:

• Sine: Sine gradually adds and decreases volume smoothly for an easy and subtle tremolo.
• Square: Much more pronounced than sine, square wave has a more on-off pattern.
• Random: Uses sample and hold that picks new random values at an interval set by the rate control.
