Walrus Audio Fundamental Series 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.

Use the Rate slider to set how fast or slow the LFO is oscillating. A lower rate gives a gentle wavering texture, while a higher rate gives a rapid pulsating effect.

The Depth slider controls the strength of the tremolo effect. Move the slider to the left for subtle tremolo or to the right for maximum chop.

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

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

• Sine: Gradually adds and decreases volume smoothly for a 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.

For the Fundamental Series, the team at 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. Each Fundamental pedal has three sliders 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 Oklahoma City, USA.
