Walrus Audio / Fundamental Tremolo

The Fundamental Tremolo is the best optical tremolo that gives iconic and rich movement.

Slider control
・Adjusts the rate of oscillation of the RATE LFO. Low values give a gentle oscillating texture, while high values give a rapid, pulsating effect.
・DEPTH Controls the strength of the tremolo. Move the slider to the left for a subtle tremolo, and to the right for maximum effect.
・VOLUME Controls the overall volume.
