The Flanger effect pedal works by taking the audio signal and mixing it with a delayed, pitch modulated copy of itself. The Flanger is similar to the Chorus effect pedal and can be used to give sounds a sweeping effect.
*delay - Allows control of the Flanger's short delay.
*feedback - Allows control over how much of the processed signal is feed back into the effect.
*speed(LFO) - Allows adjustment of the speed of the phasing effect.
*depth(LFO) - Increases the amplitude of the LFO.

Good for metallics if you don’t mind the sweeping
A slight bypass, though it sounds kinda weird:
Speed all the way up, adjust the other knobs to your liking.
Oh wow, that's quite interesting. Very good tip
