The Mr. Black Supermoon Eclipse takes the highly regarded original circuit—Mr. Black Supermoon—and expands it into a true-stereo format. Switchable via the mode button, Supermoon Eclipse users can choose to engage both the original Supermoon and Supermoon Chrome circuits. Your favorite presets can be saved with the click of a button, and the Supermoon Eclipse also accommodates an expression pedal, which can be assigned to any or all of the control knobs.
