<p>From MXR:</p>
<p>This pedal is Zakk Wylde's secret weapon for thickening up walls of distortion and adding liquid dimension and texture to clean passages.<br /><br />This pedal is powered by a single 9-volt battery (remove bottom plate to install), a 9-volt AC adapter such as the Dunlop ECB003, or an MXR Brick Series power supply.</p>
