The MXR Carbon Copy Analog Delay is one of the most popular analog delays on the market. With the M292 Carbon Copy Deluxe variant, MXR has tuned and lowered the bestsellers: the delay time has been increased to 1.2 seconds for an analog delay, the Tap delay function can be used to adjust the delay to the song tempo. Also four different subdivisions (dotted eighths, eighths, triplets and sixteenths). If you prefer the sound of the Carbon Copy Bright model - no problem, the Carbon Copy Deluxe can be switched to Bright mode. The delay signal can be modulated to produce warbling band echos or chorus effects. Also the connection for an expression pedal which can operate various functions remotely is very cool. The Carbon Copy Deluxe also has internal values: the input level can be switched internally from instrument to line level via DIP switch and fine-tuned by trimming potentiometer - a Kill Dry function can be switched to operate in a parallel FX loop.
