With MOSFET clipping under the hood, the MXR Super Dynamic O.D. generates a smooth purr that can be pulled back for a nice, clean boost or cranked into full gear for vintage high-gain grind.

This pedal is powered by one 9-volt battery (accessible via battery door on bottom plate), a 9-volt AC adapter such as the Dunlop ECB003/ECB003EU, or an MXR BrickTM Series power supply.
