MXR¨ RAW DAWGª OVERDRIVE EG74 A custom circuit, this pedal is based on a classic OD famous for its grit and crunch—but we balanced out the midrange and bumped up the gain for a sweeter, more natural sound even when cranked. This pedal can be powered by a Dunlop ECB003 9-volt adapter, or the DC Brick™, Iso-Brick™, and Mini Iso-Brick™ power supplies (not included).
