The Fender Runaway Feedback Pedal is a natural feedback simulator that lets guitarists create feedback-type sounds easily and at any volume. Developed as a collaboration with Softube, the feedback effect can be added and controlled simply by adjusting the controls and engaging the "expression pedal" which responds to vibrato, bends, slides and tremolo. Controllable harmonic content and "wet only" signal options add great tonal flexibility to a pedal that encourages creativity, experimentation and fun.
