Analog Shimmer: Vintage 1980s Ibanez CS-9 Stereo Chorus
Experience the lush, organic modulation that defined an era. This original Ibanez CS-9 Stereo Chorus from the legendary "9-Series" is the real deal—a far cry from the thin, digital emulations of today. Made in Japan in the early 1980s (Maxon-built), the CS-9 is widely considered one of the warmest and most musical chorus pedals ever produced.
Unlike the common CS-505 that preceded it, the CS-9 offers a more versatile, wider sweep that can go from a subtle "is it even on?" thickening to a deep, rotary-style swirl.

The Tone: Classic 80s Lushness

Dual Outputs: True stereo operation. Plug into two amps for a massive, three-dimensional soundscape that fills the room.

Warm Bucket Brigade (BBD) Delay: This pedal uses analog BBD chips to create its modulation, resulting in a natural high-end roll-off that sounds "expensive" and never harsh.

Controls:

Speed: From a slow, majestic wash to a fast, vibrato-like shimmer.

Width: Controls the depth of the sweep—crank it for that signature 80s "New Wave" saturation.

Condition & Authenticity

Provenance: This is a genuine Made in Japan unit. The bottom label features the iconic silver serial number plate (Serial #209864) and the original Maxon-style instructional text.

Aesthetics: This pedal shows honest "player's wear." The distinct purple finish has small chips and nicks around the edges, and the silver footswitch plate has a light patina—proof that this unit was too good to stay in a box for 40 years.

Functional Note: The battery compartment door is intact and fully functional (a rarity for these models!). The LED is bright, the pots are clean, and the footswitch is responsive.

Based on the serial number 209864 visible on the silver label in your photos, we can pinpoint the production date quite accurately.
For original 1980s Ibanez 9-series pedals (like the TS-9, AD-9, and your CS-9), Ibanez used a 6-digit serial number format where the first digit indicates the year of manufacture within the 1980s decade.
Dating Breakdown: Serial #209864

The First Digit ("2"): This stands for 1982.

The Remaining Digits ("09864"): These are the consecutive production numbers for that year.

Production Era: Because it has the silver label and a serial number starting with 2, this is a confirmed first-era original production unit.
