AWS Vintage Phaser is a 4-stage allpass phaser — the architecture that defined the psychedelic era. An LFO sweeps the notch frequencies while feedback adds resonance and squelch. Simple, effective, unmistakable.

What It Does

Phasers create moving notches in the frequency spectrum by running audio through allpass filters. An LFO sweeps those notches up and down, creating the classic whoosh sound. Feedback wraps the output back to the input, emphasizing the effect and adding character.
