he Spark Distortion Pedal may appear simple and tiny, but it features 3 controls for you to flexibly shape your effect with. The controls include Volume, Tone and Drive which are all conveniently placed in a line across the top of the pedal for easy access. The Volume control is self explanatory and lets you adjust the output of the effect, the Tone knob lets you shape the overdrive, and Drive is for controlling the intensity.
