How To Dial Up Great Guitar Sounds Using Your MXR Carbon Copy Analog Delay Pedal

By Edited Nov 13, 2013 0 0

Electric guitarists tend to be very non-technical, instant gratification types of people.  As such, they like their guitar pedals to be very simple to use.  That's why very few pedals have more than three knobs or buttons.  But sometimes even three knobs can be intimidating.  The only way to get past these fears is to spend some time learning what the controls on your guitar pedal do.  As an example, let's look at how to dial up great sounds using your MXR Carbon Copy analog delay pedal.

Insert the Carbon Copy into your signal chain.

The simplest way to do this is to plug your guitar directly into the Input jack of the Carbon Copy.  Then connect the Output jack of the Carbon Copy directly to the Input of your guitar amp. 

If you have other pedals in your signal chain you will need to decide where to patch in the Carbon Copy.  The general rule of thumb for guitar signal chains is dynamics processing (compressor/limiters), followed by distortion/boosters followed by modulation processing (delay/reverb).

Understanding what each control does


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


The Regen knob allows you to adjust the number of delay repeats from one (fully counter-clockwise) to infinite (fully clockwise).  This control works in conjunction with the Delay knob so the amount of Regen varies based on your Delay setting.


The Mix knob allows you to vary the amount of delayed, or "wet", signal from fully dry (fully counter-clockwise) to equal amounts of wet and dry (fully clockwise).


The Mix knob allows you to vary the amount of delayed, or "wet", signal from fully dry (fully counter-clockwise) to equal amounts of wet and dry (fully clockwise).

There are two internal trim pots that allow you to adjust the width and rate controls of the modulation effect.

Effect on/off switch

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

Some suggestions

Start with the Delay and Mix knobs set fully 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. 

Whatever your approach to using guitar pedals is, don't be afraid to just twist the knobs on your Carbon Copy to see what happens.  Some of the best guitar tones were created by accident.
