Seller's description

The Boss CE-300 Super Chorus is a vintage 19-inch rackmount analog chorus processor from the mid-1980s, made in Japan. Designed for studio and stage use, it delivers the warm, spacious modulation associated with classic analog Boss chorus effects, with considerably more control than a conventional compact chorus pedal. The CE-300 uses two independent chorus circuits to create a wide, full stereo effect, while mono operation can produce a deeper, more concentrated chorus character. The front panel provides Input Level, Modulation Rate, Modulation Depth, Chorus Tone and Chorus Level controls. This allows precise adjustment of everything from gentle, smooth modulation to deeper and brighter chorus textures. Built-in noise-reduction circuitry helps maintain a clean signal even with more pronounced effect settings. Stereo outputs make the CE-300 particularly effective for creating a broad spatial image with two amplifiers, a mixing console or studio equipment. Direct Mute and Effect switching provide additional control over the processed and direct signals, while a remote connection allows the effect to be switched externally. Its 1U 19-inch format reflects the professional rack equipment designs of its era. This example was made in Japan, has serial number 535460 and is configured for 220-volt AC operation.
