INVENTORY #58810

BRAND: Electro-Harmonix

MODEL: Poly Chorus Analog Flange / Chorus

FUNCTION: Guitar Effects Pedal

PRODUCT DESCRIPTION: This listing is for an Electro-Harmonix Poly Chorus Analog Flange / Chorus Effects Pedal. The Electro-Harmonix Stereo Polychorus is a versatile analog modulation pedal that combines chorus, flanging, and short delay into a single unit. Renowned for its association with Kurt Cobain and Adrian Belew, it is frequently used to recreate iconic Nirvana guitar tones, particularly those from the In Utero era.

SPECS:

• Chorus: Delivers lush, sweeping analog chorus ranging from subtle shimmers to deep, "seasick" pitch modulation.
• Flange: Produces a rich, "whooshing" comb filter effect that is highly responsive to the feedback control.
• Filter Matrix: Disengages the automatic sweep of the flanger, allowing for manual tuning of a fixed comb filter to create unique "chime" effects.
• Double Track: Functions as a short-delay slapback echo, ideal for adding space and width to the signal.
• Circuitry: All-analog signal path for warm, organic modulation.
• Outputs: True stereo outputs for immersive soundscapes and dual-amplifier setups.
• Controls: Knobs for Feedback, Tune/Delay, Width, and Sweep Rate, plus a Sweep Filter toggle for smoother sounds.
• Power: Typically requires a 9.6V DC-200mA power supply (usually included), though vintage versions used different voltages like 24V.
• Chassis: Housed in a rugged, die-cast metal enclosure for durability during live use.

ACCESSORIES INCLUDED: This item comes as seen in photos and includes its original EHX power supply.
