With a circuit based around the Panasonic MN3207 Bucket Brigade IC, the Maxon CS-9 Stereo Chorus Pro pedal chorus’s effect is bold and resonant without sounding harsh. Unlike the somewhat sterile sounds of its 80’s predecessor, the CS-9 Pro has an edgy, almost grainy quality that keeps your tone articulate and prevents wash-out.

The CS-9 Pro’s custom-tuned oscillator circuit provides enough speed for authentic rotary speaker simulation, and just the right amount of modulation for a lush vibrato that won’t leave you feeling queasy. With its Delay Time control the CS-9 Pro can venture into Flanger territory, adding a resonant, hollow quality to the effect that’s great for solos.

A top-mounted Blend control allows you to adjust the level of the Chorus effect to set it back in the mix against your dry signal. A unique feature of the CS-9 Pro is its ability to create spatial effects that add dimension to your guitar tone without the traditional Chorus wobble.

With Speed and Depth set low and the Delay Time at max, the Pro thickens your sound much in the manner of a double-tracked guitar, adding girth and life without excessive modulation.
The CS-9 Pro features stereo outputs for mono, stereo, or inverted mono signal routing.
