Description
Meet the MXR M299 Carbon Copy Mini, a compact powerhouse that packs the organic analog warmth and ease-of-use of the renowned Carbon Copy series into a mini pedal format. This pedal is a rock 'n' roll staple, adored by guitarists worldwide for its rich bucket-brigade warmth and elegant simplicity.
In its default mode, the M299 produces the same dark, mellow wash that made the Carbon Copy Analog Delay famous. For those desiring more sparkle and clarity, the added Bright switch accentuates high-end frequencies, resulting in increased presence and vocal-like repeats.
The M299 Carbon Copy Mini also comes equipped with the same modulation section as its predecessor. Engage the Mod switch and adjust the internal Speed and Depth controls to add anything from subtle tape echo warble to shimmering, liquefied chorusing to your repeats.
Whether you're a weekend warrior, a recording pro, or someone looking to downsize their pedalboard for travel gigs, the MXR M299 Carbon Copy Mini is an excellent solution.

Simple and great sounding
Gotta love 3 knob pedals. From all the way down to around 2 o'clock on the delay knob the repeats sound great. Past 2 o´clock repeats become more gritty and drop volume, also noise and aliasing artefacts increase, actually I never heard these artefacts on the original version tho. For me past 2 o'clock is not really usable, only for ambient/psychedelic stuff. Regen oscilation is very predictable and controllable, and the trails have that distinct Carbon Copy filtering which sound super cool. The bright switch is a great bonus, I feel like it boosts a bit of the highs and definitely cuts low end, so it has more of a tape echo vibe to it, after alternating monthly between both modes I think I settled in the bright mode, for my own surprise. Modulation works great, I like to just set it to slowish rate and lowish depth for a subtle moody movement. It feels super well built and the knobs have a nice tough drag (maybe a bit to tough for such tiny knobs) and feel high quality, the pointers glow in the dark. Only thing I can complain is that tiny son of a gun of the bright switch, once you engage i's kinda hard to disengage it, you really need a super small screw driver or toothpick to take it out or else you will ruin it very soon... Would much prefer to see other type of switch, like the modulation switch, maybe someday I will try to mod it. Oh, and it comes with a power supply, adding nice value to the purchase, 188€ in Portugal. A bit on the expensive side. Anyway, if you want mini delay pedal and don't need modulation I would recommend the Ibanez Mini Delay.
Edit: I just noticed it comes with the more recent Bucket Brigade Chips by Cool Audio V3205D (like the SD Vapor Trail and Boss DM2W) instead of the old Beilling BL3208. Dunno how that affects overall sound though since I never tried the original Carbon Copy. You can check it in this image https://frankmeffert.de/wp-content/uploads/unnamed.jpg

Full Size is Great, Mini is Greater
I actually sold my original full-size Carbon Copy so I could gain some space back on my main pedalboard. This thing has all the features of the original, and takes up far less space.
It's an analog delay, so there are functional limitations to the delay effect itself. One example being you cannot summon up the infinite blackhole looper-like delay that you could with a digital delay, but that's not a downside. That's not why you want to toss one on your board. Those mild, more musical types of delays that guitarists have used throughout history is what this reminds me more of. It makes it so much more desirable for my purposes, because I'm not the kind of guitarist that strings together 19 different pedals to essentially make my guitar play itself.
There's a certain tactile connection with this delay, you can get a really tight, short ricochet effect, or draw out the longer trails and create really interesting soundscape for those lead moments. It just really responds to more of a "guitarist's guitarist" style of playing versus the cosmic arcade drone playground style.

Deluxe Carbon Copy in nano size
It has all the bells and whistles of the classic Carbon Copy with modulation, high pass option anad glow in the dark indicators on the knobs. One disadvantage shared with the the regular carbon copy is the modulation controls are accessed internally on the back of the circuit board.
