an Ibanez brochure

The chorus effect uses a small time delay that is varied to producte 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. The CS9 Stereo Chorus provides stereo outputs that add an exciting dimension of movement to the second. The sweep speed and width controls allow the artist to illicit slow, wide-ranging sweeps or a more rapid vibrato. The CS9 Stereo Chorus - the industry's finest realization of an exciting new sound.

Ibanez about the reissue

When it comes to compact effects, nine is the magic number. By popular demand (and the understandably escalating prices of the originals), we're reissuing two of the most popular Ibanez 9-Series effects, the FL9 Flanger and CS9 chorus. If you missed out on getting one of these classics the first time around, now is the time.
