The Flanger
The Flanger is basically a Comb Filter with adjustable feedback, which can be used for creating a wide variety of cho-
rus effects and frequency swirls. The principle is to split the input signal in two, run one signal dry and the other
through a comb filter delay, and then sum the two signals. The picture below shows the basic principle of a flanger:
Frequency
Here you set the comb filter frequency (in practice, the delay time between the dry and processed signals).
