Up for sale, a 1995 Maxon CS-550 Stereo Chorus in mint condition and in perfect working order, complete with the original packaging and power supply. Based around the Panasonic MN3207 Bucket Brigade IC, this late ‘70s-flavored chorus effect is bold and swirling. In contrast to the sterile chorus sounds of the ‘80s, the CS-550 has an edgy, almost grainy quality that maintains articulation and prevents wash-out.

The CS-550’s custom-tuned oscillator circuit, based on the Boss CE-1, provides enough speed for authentic rotary speaker simulation, and just the right amount of modulation for a lush vibrato that doesn't cross over into queasy, sea sickness-inducing territory. The Delay Time control has a wide sweep, enabling the pedal to venture into Flanger territory and adding a resonant, hollow quality to the sound that's great for solos and lead work. A rear-mounted Blend mini-knob allows the player to adjust the level of the Chorus effect in relation to the dry signal. The CS-550 also has stereo functionality, with output for mono, stereo, or inverted mono signal routing, as well as true bypass switching.

A unique feature of the CS-550 is its ability to create “spatial” effects that add dimension without the traditional Chorus wobble. With Speed and Depth set low and the Delay Time at max, the 550 thickens the signal much in the manner of a double-tracked guitar, adding girth and life without excessive modulation.

This CS-550 is in mint condition with pristine graphics. The serialized sticker on the baseplate dates this pedal to 1995.

The original box, protective plastic, paperwork, and power supply are included.
