Submitted on February 11, 2005

Controls

Speed
controls the speed/rate of the LFO wave that controls the flanger
Regen
controls the feedback/resonance of the flanger
Width
controls the depth/amplitude of the LFO wave that controls the flanger
D-Time
controls the center amount of delay of the flanger

If you are looking for a flanger that will give you years of continuous service, yet not cost you an arm and a leg, check out an Ibanez SF10. It's BBD circuitry delivers rich, smooth flanging effects that will enrich the tone of any electronic instrument. The SF10 features four control knobs that give you complete control of the delay time, speed, width and feedback of the effect, allowing you to produce an almost unlimited array of flanged effects.

Principle

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.

Use

Although virtually identical in theory and operation to a digital flanger such as the DCF10, the analog circuitry of the SF10 creates a uniquely rich and warm sound. Since the delayed signal is slightly different from the original, unique patterns of resonance and phase cancellation occur. The SF10 is especially suited for flanging distortion guitar sounds.
