Poly Chorus
The Electro-Harmonix Poly Chorus is a legendary analog multi-modulation pedal renowned for its lush, experimental, and versatile sonic palette. Originally released in the 1970s and later reissued in various formats, including the Stereo Polychorus, it has become a staple for iconic guitarists like Kurt Cobain and Adrian Belew. The pedal is celebrated for its ability to generate an array of modulated soundscapes, offering four selectable modes: Chorus, Flange, Double Track (a short slapback echo), and Filter Matrix. Key technical features include continuous control over feedback, rate, width, and tune/delay, allowing for everything from subtle shimmering textures to chaotic self-oscillation and "alien" noises. Its analog circuitry, often utilizing vintage bucket-brigade device (BBD) chips, provides a warm, organic character. Housed in a rugged die-cast chassis, the Poly Chorus remains highly sought after by collectors and musicians seeking to replicate classic "In Utero" tones or push the boundaries of conventional modulation.
