7.4.13. Flanger

The Flanger is the most intense of the time/modulation effects. It originally came from
audio engineers gently pressing on the flange (rim) of a moving tape reel to slow down
the playback a tiny bit. When combined with the original sound, this effect produced comb
filtering , a set of regularly spaced notches in the frequency response that look like the teeth
of a comb. Varying the pressure on the flange would cause the notches to move, producing
the effect we hear as flanging. Later, analog delays controlled by an LFO were used to
create the same sort of effect.
RATE is the speed of the LFO that varies the delay time. It can be set without sync
•
or with different types of sync, as explained in
1/32 bar to 8 bars)
DELAY is the length of the basic delay, which is modulated by the LFO and
•
spread out by the Depth knob. Flanger delays are the shortest of any modulation
pedal – longer delays become chorus, then echo. Originally called Manual on
early flangers, this parameter sets the overall tonality of the flange from bright
to dark. (0.001 to 10.0 ms)
DEPTH is the amount of variance in the set delay time. (0.00 to 10.0 ms)
