“A flanger, such as the Ibanez SF10, makes it’s effect by mixing dry and short delayed signals together. These signals are mixed in a way that causes a moving group of frequencies to drop out, forming a moving comb-filter.”
“The range in which the comb-filter moves is controlled by the Width knob, where as the rate at which it moves is controlled by the Speed knob. The Regen knob controls the amount of feedback. Turning this CW intensifies the effect.”
“When the delay time is shortened by turning the D-Time control CCW, the overall effect becomes more metallic in sound.”
