Then, the signal goes back into the . This is the expander . Remember how we compressed the signal earlier? The expander does the opposite. It turns quiet signals down and loud signals up to restore your original dynamics.
If you ask ten guitarists to name their favorite analog delay pedal, chances are at least four of them will say the MXR Carbon Copy . Since its release in 2008, this bright blue box has become a modern classic, beloved for its dark, smeared repeats, the lush modulation available at the flick of an internal switch, and its remarkably simple three-knob interface.

Crucially , this stage also contains the (the opposite of the input pre-emphasis). It cuts the highs back down to normal, simultaneously removing the hiss we were worried about earlier. Section 5: The Mixing Amplifier The Carbon Copy is unique because it is a 100% wet mix pedal . Many delays blend internally. In this circuit, your dry guitar signal goes straight to the final output stage via a buffer. Then, the signal goes back into the
Keep building. Keep tweaking. Keep the analog dream alive. The expander does the opposite
