Auto Wah. Kosko Series

A psychedelic modulation effect inspired by the original Park Auto Wah circuit.
This is not a dynamic envelope filter — it’s a true LFO-controlled auto-wah, where the movement happens independently of your picking. The result is a consistent, hypnotic sweep that brings unmistakable ’60s character to your tone.
With Speed, Tone, and Depth controls, you can shape everything from gentle, rolling waves to sharp, aggressive pulsations. Adjust the modulation rate, filter brightness, and intensity to dial in textures ranging from subtle vintage swirl to bold, acid-like movement.
Perfect for psychedelia, garage rock, stoner vibes, and experimental textures that demand motion and personality.
Swirling. Expressive. Unmistakably retro.
