The MXR M299 Carbon Copy Mini Analog Delay is a compact analog delay pedal that adds warmth, depth, and dimension to an electric guitar or bass signal. It recreates the classic sound of vintage analog delay units in a smaller enclosure, making it ideal for musicians who want rich, musical echoes without taking up much pedalboard space.

Unlike digital delay pedals, which can produce very precise and clear repetitions, the Carbon Copy Mini uses an analog bucket-brigade delay circuit to create repeats that gradually become softer and darker. This gives the effect a smooth, organic character that works particularly well with clean tones, overdriven guitars, ambient textures, and classic rock sounds.
