Small in size and innovative in design, the Mooer Spark Distortion is essentially the size of a button and features controls on the front of the pedal rather than the top to save space. The Spark is a true bypass pedal that serves up a hot, modern distortion, with the option to hit the front-panel boost switch to turn the heat up even higher. And with knobs for tone, gain, and level, the Spark offers far more tweakability than its size would indicate.
