MXR M299 Carbon Copy Mini Analog Delay Pedal Review (May 2024)


Last updated on May 26, 2024 6:40 pm Details


In this review post, we’re going to be discussing the MXR M299 Carbon Copy Mini Analog Delay Pedal, including an overview of its unique features.

Product Description

In just over a decade, the MXR Carbon Copy Analog Delay has become a rock ‘n’ roll staple. Its rich bucket-brigade warmth and elegant simplicity have endeared it to guitar players around the world—weekend warriors and recording pros alike. It’s the go-to standard for players who want a well-rounded, easy-to-use delay pedal that sounds incredible. Between the Carbon Copy Analog Delay and Carbon Copy Deluxe Analog Delay, you can find a solution for almost any of your delay needs—but if you’re looking to free up some space on your own board, or downsize to a smaller one for travel gigs, then consider another demand met.

The Carbon Copy Mini Analog Delay packs organic analog warmth and ease of use into an MXR mini housing with added sonic versatility so that you can make the most out of your pedalboard real estate. In its default mode, this pedal’s repeats yield the dark, mellow wash that made the Carbon Copy Analog Delay famous. For players who want more sparkle and clarity, we added a Bright switch that accentuates high-end frequencies for increased presence and distinctively vocal repeats. And of course, the Carbon Copy Mini Delay is outfitted with the same modulation section as its forebear. Push the Mod switch and adjust the internal Speed and Depth controls to add everything from tape echo warble to shimmery, liquefied chorusing to your repeats. Finally, adjust the parameters of your delay signal with the Regen, Mix, and Delay controls.

Our Verdict

As a result, the moment has come for creative individuals to dust off ancient BBD technology and make fresh copies of the real item rather than a digital recreation of it.

MXR is indeed the latest to release a new analog delay, the Carbon Copy, which has echoes of the previous MXR Analogue Delay (discontinued in the 1980s), not least in its three control knobs and greenish coloring, but in a much spanglier metallic hue this time.

The Carbon Copy features the same knob settings as any other analog delay – old or modern – on the market, but the modulation offers extra flexibility. With modulation turned on, the effect is extremely modest, but if you go into the innards, you can tweak the trim pots for more diffused repeats that resemble the warble of a tape echo. There isn’t much that can compete with this pedal as a mass-market analog delay in a convenient-sized box.

Great sounds in a small package – fantastic.
