Butter Yellow Auto Quack

The Butter Yellow Auto Quack delivers smooth envelope filter sounds for funky, expressive playing. The circuit responds to your pick dynamics with quacking filter sweeps.

The auto-wah tracks your playing intensity to control the filter. Harder attacks trigger more dramatic sweeps. The smooth response suits funk, R&B, and expressive lead work.

Sensitivity and range controls shape the filter response. The yellow coloring suggests the smooth, buttery character. Compact format handles funky sounds efficiently.
