8 BLOCKS GUIDE
Feedback
– This is the famous “regeneration” control discussed above. Feedback sets the amount of wet signal
fed back to the input of the flanger. Extreme values give the flanger a more intense quality as it produces sharp
singing resonances or clanging metallic overtones.
Note that Feedback ranges from -100 to +100. Negative values invert the signal phase in the feedback loop,
creating sounds with a different character that is more hollow-sounding and vocal (almost like the sound of
oscillator sync on a synthesizer (e.g. “Why Can’t this be Love” by VH or “Let’s Go” by The Cars). In either direction,
extreme feedback settings may cause a siren-like ringing oscillation.
Low Cut
,
High Cut
– These filter the wet portion of the effect signal, gently rolling off lows or highs at the set
frequency with a slope of 6db.
Drive
– This control allows you to simulate the soft distortion produced by overdriving an analog “bucket brigade”
delay chip of the type used in many vintage flanger effects. Set to zero for “pristine clean.”

LFO Type
– Sets the shape of the modulation waveform.
LFO Phase
– Adjusts the phase difference between the left and right LFO waveforms. For maximum stereo
spread, set this to 180 degrees. For mono flanging, set this to zero.

“LFO Waveforms & Phase” on p. 135 .
LFO Bypass Reset
– This allows you to force the flanger to start from a fixed point in its sweep cycle when you
engage the effect. With the default value of “Off” the Flanger LFO will cycle freely, even when the effect is off.
LFO Hicut
– Lowering this control filters the LFO waveform, rounding the edges of sharp turns in its shape. The
highest setting of 100Hz is basically unfiltered. Certain waveform types (saw, square, random) can otherwise
cause clicks or pops as their values jump from one extreme to another. When you adjust the Rate of the flanger,
you may need to re-visit this setting. A slower LFO needs a lower Hicut setting to preserve the same effect.
Auto Depth
– Scales Depth to create a consistent sound at any Rate. This control simplifies dialing in the sweet
spot, but for precise control or wild sounds you may wish to turn it off.
Through Zero
– Setting this to ON adds a delay to the dry path equal to half the sweep depth. This can emulate
true tape deck flanging, where one of the two tapes is first ahead of, and then behind, the other.
Dry Delay
– When Thru Zero (above) is engaged, this allows shifting the cancellation point from the center of the
waveform to the edge or anywhere in between.
Phase Reverse
– Controls the phase of the wet output signal. Either or both channels can be inverted. Use to
increase the effect of through zero flanging.
Stereo Spread
– Controls stereo width by setting the pan position of the two delays from hard panned (100%) to
dead mono (0%).
