Electro-Harmonix Stereo PolyphaseTHE ULTIMATE ANALOG OPTICAL PHASE SHIFTER ENGINE.CREATIVE LFO MODULATION AND ADVANCED ENVELOPE FOLLOWING.Original owner. Non-Smoking studio.The bottom of the pedal and the bottom of the sides have some discoloration and slight texture from stage usage, otherwise the pedal is in perfect working order and has hardly been used. The bottom plate discoloration is the only reason it is not listed as being in "Excellent Condition". Introduce a highly unique, expressive evolution of the phaser to your signal chain with the Electro-Harmonix Stereo Polyphase. Finished in a road-ready classic chassis, this analog optical powerhouse goes far beyond basic modulation pedals by combining traditional LFO-driven phase shifting with dynamic envelope-following controls. It utilizes high-quality optical circuitry to shape your guitar, bass, or synthesizer signal into incredibly rich, liquid-smooth harmonic sweeps, leaving you with an organic, responsive, and articulate modulation effect that tracks beautifully across all frequencies, making it an incredible choice for dynamic studio tracking, spacious stereo textures, and cutting-edge ambient soundscapes.FeaturesThree Selectable Operating Modes: Driven by an all-analog core to deliver classic LFO modulation, an expressive dynamic Envelope Follower, and a hands-free manual Expression Pedal sweep mode.Variable Waveform LFO Vector: Features switchable Triangle and Square wave modulation modes alongside independent Rate and Start/Stop controls to dial in everything from slow, lush pulses to dramatic, choppy rhythmic steps.Advanced Envelope Tuning Controls: Incorporates specialized Sensitivity and Feedback parameters that dictate the response threshold and resonance intensity, allowing you to fine-tune exactly how the optical sweep reacts to your playing dynamics.True Stereo Performance Outputs: Equipped with independent Main and Stereo outputs to split your phase-shifted signal across a dual-amplifier configuration for massive, wide-panning spatial landscapes.Expression and Control Voltage Input: Integrates a dedicated 1/4" expression pedal input that handles TRS control cables or synthesizer control voltages, shifting real-time command over the filter sweep directly to your feet or external gear.Includes original EHX 12V power supply.
