The MXR Carbon Copy is a beloved analog delay pedal known for its warm, rich repeats and straightforward control layout. Featuring Bucket Brigade Technology (BBD) circuitry, it delivers lush, organic echo tones with up to 600 ms of delay, from subtle slapback to dreamy ambient washes. Simple knobs for Delay, regen (feedback), and Mix make it easy to dial in classic delay sounds, and an optional modulation switch adds a gentle chorused movement to the repeats. Rugged and easy to use, the Carbon Copy has become a staple on pedalboards across genres for players who want classic tape-like delay character in a compact stompbox.
