MXR Carbon Copy Analog Delay — one of the most popular analog delay pedals ever made, loved for its warm, all-analog bucket-brigade tone. Goes from tight slapback echo to long, lush Gilmour-style repeats with just three simple controls: Delay, Mix, and Regen. Optional modulation switch adds subtle warble and depth to your repeats. True bypass keeps your tone unaffected when off. Compact, road-tested, and a staple on countless pedalboards.
