The Q Cat is an Envelope Filter with all the right ingredients for dialing in your preferred filter tones. The Resonance knob lets you dial in the quack. Pull it back for a lighter Wah type tone or crank it for a more intense effect. The frequency knob adjusts the filter from sharp and bright, to a low end rumble. The Q Cat works great for single coil and Humbucker equipped guitars.
