5.5.9 Comb
Comb Filter
Comb lters change the sound by delaying the signal by a few milliseconds and then mixing
the delayed signal with the original. As a result, the level of certain frequencies may be raised
or attenuated in the ltered signal.

Effects such as the phaser and the anger use this phenomenon. By modulating the Comb’s
parameters, you can quickly produce a nice anging effect.
Main Panel
The Comb Filter has the following parameters:
• FrequencycontrolandFrequencymenu: The Frequency control allows you to set the cut-
off frequency in semitones (Trans) or in Hertz (Hz), upon the selection in the nearby
Frequency menu.
•
Feedbackcontrol: Sets the amplication factor for the delayed signal. Higher values induce
steeper frequency peaks/cancellations.
• Dampingcontrol: Allows you to balance out any level uctuations introduced by the lter
(in dB).
