The MXR Carbon Copy provides a delay time of up to 600ms. With the modulation switch that sits on top of the device and the internal trim pots, you are able to create unprecedented delay tones. The Carbon Copy has an all analog audio path that delivers warm delay sounds. The 3-knob layout design with Delay, Mix, and Regeneration makes this pedal very easy to work with, and when combined with the modulation switch, you are looking at a wide range of sound possibilities, from a fairly compact pedal. We invite you to take the MXR Carbon Copy M169 for a ride on the TonePedia player and find out why it is one of the best selling delay pedals out there.
