Flickering tremolo

The "FLIKRRR - flickering tremolo" (FLK) is a tremolo effect pedal inspired by the natural patterns and fluctuations found throughout nature.

Styled upon the natural phenomenon known as 1/f fluctuation, it is characterized here by gentle swaying tremolo patterns.

You can make volume changes reminiscent of the soft sway of a candle flame, or the flicker of a fluorescent lamp.
