Dunlop produced the M299-U MXR Carbon Copy Mini Analog Delay as a compact version of the Carbon Copy analog delay, housed in an MXR mini enclosure. It occupied the analog delay category of the MXR effects line, offering a reduced footprint for space-conscious pedalboard configurations.
The pedal delivered analog delay with modulation capability. Delay time ranged from 20 ms to 600 ms, and modulation speed ran from 0.2 Hz to 2.2 Hz. A Bright switch provided an additional tonal option. The unit featured true hardwire bypass, drew 26 mA, and ran on a standard 9-volt DC power supply. Input impedance measured 1 MΩ and output impedance 1 kΩ, with a maximum input level of +5 dBV at 500 Hz and a maximum output level of +8 dBV. Noise floor measured -96 dBV with the mix control at maximum clockwise and -104 dBV at maximum counter-clockwise. Delay distortion came in at under 1% at 1 kHz with a -5 dBV input, and onboard noise reduction operated at a 2:1 ratio.
Owners requiring adjustment, repair, or power supply compatibility verification should consult a qualified guitar technician familiar with compact effects units.
Nothing in The Vault is for sale. These records exist so the instruments stay documented after the manufacturer moves on — and the most useful part of that record is what owners add to it.
The catalog shot showed one finish, under one light, a long time ago. Yours has been played. Photos from owners are what the next person finds when they are trying to identify a part, match a finish, or work out whether the one they just bought is really what the seller said it was.
Specs only go so far. What actually fits, what breaks first, what the factory got right and what everyone ends up changing — that lives with the people who own them, not in a datasheet. Post what you know and it stays on this page for whoever comes looking next.
