Rocking Out With The MXR Carbon Copy

As a whole, electric guitarists tend to favor uncomplicated gear. As such, the ordinary guitarist will most likely choose simple stompboxes. That's probably why very few guitar pedals have more than three knobs or buttons. In fact, there are a few players that feel three knobs are even too many. If this sounds like you, just face it, you're going to have to take some time and teach yourself what the knobs on your guitar pedals do. A great place to start learning how to dial in your own sounds is with a delay stompbox like the MXR Carbon Copy.

Insert the Carbon Copy into your signal chain.

Instead of just plugging your guitar directly into your amp, you need to plug it into the Carbon Copy first. Plug the output of the Carbon Copy to the input of your amp.

If you have more than one stompbox in your signal chain you will need to determine where to patch in the Carbon Copy. Most guitarists put delay pedals at the end of their signal chain.

Understanding what each control does.

Delay:

The Delay knob allows you to set the amount of delay time from 20ms (fully counter-clockwise) to 600ms (fully clockwise).

Regen:

The Regen knob allows you to modify the total number of delay repeats from one (fully counter-clockwise) to infinite (fully clockwise). This knob works together with the Delay knob, changing the amount of Delay changes the amount of Regen.

Mix:

The Mix knob allows you to alter the portion of delayed, or "wet", signal from entirely dry (fully counter-clockwise) to uniform amounts of wet and dry (fully clockwise).

Mod:

The Modulation button allows you to impart a certain portion of modulation to the delay signal. Modulation is an effect that varies the pitch of a signal by a small, regularly occurring amount, creating a warbling effect.

Inside the Carbon Copy there are two internal trim pots that allow you to set the width and rate controls of the modulation effect.

Effect on/off switch:

Like most guitar stompboxes, the Carbon Copy has a foot-switch that toggles on and off.

Some final tips:

Begin with the Delay and Mix knobs placed entirely clockwise and the Regen knob set full counter-clockwise. Turn the pedal on by stepping on the footswitch. A blue LED illuminates when the effect is engaged. Now all you need to do is dial in your desired sound by adjusting the three knobs in relation to each other.

Don't let a lack of experience stop you from twisting those knobs. Experimentation can deliver amazing outcomes.
