Carbon Copy

Delay, Mix, and Regen sit on the face. A MOD switch adds chorus-like movement to the wet signal only. Width and rate of that modulation are set with two internal trim pots, so once dialled they stay put without cluttering the top panel.

Repeats darken and soften as they fade, which keeps slapback and medium echoes from competing with the dry note. High Regen settings can push the circuit into self-oscillation for rising feedback swells. True hardwire bypass passes the dry path when the effect is off.

There is no tap tempo or wet-signal EQ. Modulation depth beyond the internal trims is not available from the top. Available since 2008 in the classic compact MXR enclosure.
