Designed to respond organically to your playing, the Runaway Feedback Pedal tracks vibrato, bends, slides, and tremolo, allowing you to produce expressive feedback without altering your technique. The integrated expression pedal enables smooth fade-ins and fade-outs of the feedback effect, while the harmonic selector switch lets you choose between fundamental, upper fifth, or sub-octave harmonics for precise tonal shaping. *VERY RARE*
