Electro-Harmonix Classics Stereo Polychorus Analog Flange / Chorus Effect Pedal

The "Stereo" reissue of the Polychorus is a different beast than the 1980s original—it’s quieter, more reliable, and features the Sweep Filter and Overload LED that the vintage units lacked. This is the exact version used for the textures on In Utero and by experimental legends like Adrian Belew and Thom Yorke.

The Modern Classic: EHX Stereo Polychorus Reissue

This reissue delivers the thick, syrupy analog modulation that only Bucket Brigade (BBD) chips can provide. It's essentially four pedals in one, housed in the classic "big box" chassis that commands attention on any pedalboard.

Four Dynamic Modes:

• Filter Matrix: A "frozen" flanger. It disengages the sweep so you can manually tune the comb filter for metallic, resonant, and chime-like tones.+1
• Flange: Sweeping, liquid textures that go from a gentle shimmer to a full "jet plane" whoosh.
• Chorus: A lush, wide stereo chorus that adds incredible depth and a 12-string quality to your signal.
• Double Track: A short analog slapback delay that provides a massive "stadium" sound and thickened doubling.

Key Reissue Features:

• Sweep Filter Switch: A reissue-specific toggle that smooths out the modulation for a more "liquid" feel—perfect for taming extreme settings.
• Overload LED: Helps you manage your input gain to ensure the analog circuitry stays sweet and doesn't clip harshly.
• True Stereo Output: Designed to be run into two amplifiers for a dizzying, immersive 3D soundscape.
