The CS9 has 2 knobs: Speed and width. One input, 2 outputs. This chorus effect uses a small time delay that is varied to produce a slight pitch bend. When the delay signal is mixed with the input (dry) signal the resultant sound moves with a rich, thick undulation. This is the effect of multiple voices playing in unison with a fantastic, shimmery chorus sound . The sweep and width controls allow you to illicit slow, wide-ranging sweeps or a more rapid vibrato. There is a second output jack that allows you to run a line to a second amp.
