Rat Distortion

A classic distortion that inspired thousands of clones and shaped half of the alternative music scene.
This replica preserves everything players love about the original: gritty, saturated gain with a distinctive grainy texture that can function as a tight overdrive or push into aggressive, fuzzy territory. From punchy rhythm crunch to thick, sustaining lead tones, it delivers raw character and unmistakable attitude.
Responsive, dynamic, and versatile, it cuts through the mix while maintaining that iconic mid-forward growl.
Simple controls — Volume, Tone, and Distortion — give you complete command over gain structure and brightness, making it easy to adapt to different amps and styles.
Raw. Direct. Legendary.
