The MXR Carbon Copy is a simple analog delay. It has 3 control knobs and a push-button for activating the modulation option.
Dunlops Carbon Copy Delay ranges from 20ms - 600ms controlled by the Delay knob. You can control the number of repeats with the Regen knob. By rotating the Mix knob you set the dry/wet balance.
I have tested the Carbon Copy with my old german violin with the Bradivarius pickup going into the Source Audio programmable EQ.
Here is the violin recorded with Carbon Copy delay bypassed for comparison:
