The Electro-Harmonix Riddle Q-Balls Envelope Filter Pedal for Guitar is a powerful and precise envelope filter pedal for guitar frequency response. It's a unique sound modifier where the intensity of the effect is controlled by the user's playing dynamics. The volume and dynamic of the incoming audio signal are used to control a swept filter. As the volume increases or decreases so does the frequency of the filter. The filter can deliver tight and smooth control over the complete 80 Hz to 5 kHz range. This filter features three filter modes, along with Start, Stop, Attack, Decay, Q, and Sensitivity controls. You can plug in an optional expression pedal to control the filter sweep with your foot.
