The MXR Carbon Copy Analog Delay features an entirely analog audio path, delivering rich, warm delay using old-school bucket brigade technology. The Carbon Copy boasts 600ms of delay time, with optional modulation via a top-mounted switch, and its simple three-knob layout gives you complete control over Delay Time, Mix (dry/wet blend), and Regeneration (delay repeats) – all in one incredibly compact pedal !
