The Speed control adjusts the rate at which the tremolo effect oscillates. Turning it clockwise increases the speed, while turning it counterclockwise slows it down.The Intensity control determines the depth or strength of the tremolo effect. Turning it clockwise increases the intensity, resulting in a more pronounced effect, while turning it counterclockwise reduces the intensity.The Tone control allows you to shape the overall tone of the modulated signal. Turning it clockwise boosts the high frequencies, giving a brighter sound, while turning it counterclockwise attenuates the highs, resulting in a darker tone.Overall, the HF Modulator is a unique and quirky effect pedal that can add a wobbly, ring-modulator-like effect to your guitar or other audio signals. While it may not be the most musical effect, it can be a fun tool for experimentation and creative sound design.
