The CKK Electronic Q Cat Pedal brings smart filter enveloping effects to your electric guitar's sound. With a voice similar to a wah pedal, the effect uses adjustable frequencies to open and close a filter. The resonance, sensitivity and frequency knobs allow you to have precise control over your effect's sharpness. This makes it a great pedal for funk and jazz players, or for those wanting a wah-sounding pedal without having to manually adjust it whilst playing.
