The users guide was excellent. It provided the information neeeded to connect and control the Crate system. Nothing was left to chance

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°.
