The Comb effects work by combining the original input signal with a micro-delayed version. The tiny delay difference between the two signals causes certain frequencies to be cancelled or reinforced when the two are combined. The result is a highly colored version of the original source. The coloration can be �tuned� with the Comb (Comb 1) or Depth (Comb 2). Low and High pass filters are included so you can limit the frequency band in which the combing occurs. Comb 1 is a mono comb with single-pole low and high cut filters. There are two ways to get the comb effect. The first is to set mix to 100% (wet), then set Notch to 50 or -50. This essentially creates a band-limited signal (limited by LoCut and HiCut) which is then run through a comb. You can also set mix= 50%, Lvl = 0dB, and Notch= +100. In this case, the band-limiter is part of the comb. In this version, the effect produces shallower notch depths outside the bandlimit region. Comb 2 is a dual mono comb with a second tap, controlled by a single LFO with adjustable phase. The phase relation between the two waves can be adjusted between 0-270°.
