Enjoy classic, tone-preserving tremolo effects with the Fundamental Tremolo. With three selectable wave shapes, ranging from smooth and soothing to wild and glitchy, it's perfect for both pedalboard veterans and newcomers alike. Its optical circuitry faithfully retains your sound's integrity, so you can make use of its versatile tremolo capabilities.

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. Specs
