Auto Wah. Kosko Series

Psychedelic ’60s-style modulation — an LFO-driven filter inspired by the original Park Auto Wah circuit.
This isn’t a dynamic envelope filter — it’s a true auto-wah, where everything moves on its own. Speed / Tone / Depth controls let you shape the wave rate, filter brightness, and depth of the effect — from smooth sway to aggressive pulse.
Perfect for psychedelia, garage rock, stoner vibes, and acid textures.
