From MXR:

The Carbon Copy Mini Analog Delay packs organic analog warmth, shimmery modulation, and ease of use into an MXR mini housing with a Bright switch for additional sonic versatility so that you can make the most out of your pedalboard real estate.

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).
