The MXR Carbon Copy includes a Tap Tempo function plus a Tap Division feature offering four subdivisions: dotted 8th notes, straight 8th notes, triplets, and 16th notes.

It has a switchable modulation section that adds tape‑echo‑style warble and subtle chorusing. Controls listed include Speed and Width (or Speed and Depth) to adjust the modulation rate and intensity.

Primary delay-shaping controls are Regen (feedback), Mix (wet/dry balance), and Delay (delay time). Modulation controls such as Speed and Width/Depth further color the repeats.
