The MXR Carbon Copy is an analog delay pedal with up to 600 milliseconds of delay time and a selectable modulation feature. The pedal comes in MXR’s usual small form-factor, World War III-ready chassis, has three dials, a button and the obvious footswitch. There is no tap tempo feature whatsoever, but if you open up the back of the thing, there are two screws for adjusting the depth and width of the modulation.
It is not often that I try a pedal and just go, “wow”. But I did this time. This pedal just shines when you use it the way I’m forced to: before an amplifier, before distortion. (Well, I do have an effects loop, but that’s another story for another time). The TC Electronic Flashback sounded very nice, but I could never get it to balance clean and distorted sounds; I would have needed two of them. The Carbon Copy just nails the sound I want out of a delay pedal. It sounds warm and organic and just fantastic. It is also remarkably fun just to play around with! Set the regen parameter to maximum and it self-oscillates and you can go all Yngwie Malmsteen with the delay time knob. The modulation feature is a little hot right out of the box, but I am personally not planning to use it any time soon, so I don’t worry about it. As I said previously, it can be adjusted with a minimum of fuss.
One of the nicest things with the Carbon Copy is that MXR have been rather generous with the delay time. Traditionally, analog delays have had fairly short delay times, the classic Boss analog unit has 300 ms and some recent copies don’t fare much better. Double that, like with this pedal, and you get true flexibility: everything from slapback to Gilmour-like soundscapes.
One thing that might discourage the casual user is the price tag. It is a lot of money. And you don’t get the bells and whistles: no looping feature, no tap tempo, no 6 seconds of delay time. But you do get a damn well-sounding delay pedal that just works no matter how you use it. I personally prefer the slightly dirtier, warmer sound of analog to the pristine, clean digital stuff, and would rather pony up the extra cash for something that can live on my pedalboard long-term instead of being sold off within the year. Yes, and I just bought one.
