The Ibanez CS9 Stereo Chorus pedal is a vintage analog effect pedal that offers a rich and lush chorus effect. Manufactured in Japan by the Maxon corporation, the CS9 is part of the historically significant Ibanez 9 Series pedals, which have inspired many high-end boutique units and have been used on iconic recordings.
The pedal features stereo outputs, adding an interesting dimension of movement to the sound. The chorus effect is created using a small time delay that is varied to produce a slight pitch bend. When the delay signal is mixed with the dry input signal, it produces a rich, thick undulation as if multiple voices are played in unison.
The CS9 Stereo Chorus is equipped with sweep speed and width controls, allowing the artist to elicit slow, wide-ranging sweeps or a more rapid vibrato. The pedal produces a relatively subtle effect, characterized as warm, lush, swirly, and shimmering, epitomizing key sounds of the 1980s.
The technical specifications of the CS9 Stereo Chorus include:
- Input Impedance: 500K Ohms
- Output Impedance: Original: <1K Ohms, Reissue: 10K Ohms
- Maximum Input Level: +4 dBm
- Gain: 0 dB
The pedal is powered by a standard center-pin-negative 9V barrel and is designed to provide warm yet clear chorusing with utmost simplicity.
