The MXR MC402 Boost/Overdrive provides both classic overdrive and a crystal-clear, uncolored +20 dB volume boost. You can control these functions separately using the two footswitches and four knobs. MXR developed this pedal in collaboration with Custom Audio Electronics, known for creating effects systems for top guitarists. The clean boost circuit in this stompbox has been a favorite among professionals for years.

The overdrive on the MC402 delivers a vintage warm tone, adding sustain and punch without coloring your sound. It ranges from a subtle bluesy overdrive to aggressive metal distortion. The overdrive is highly dynamic, responding well to even the slightest touch when you adjust your guitar’s volume knob. Additional standout features of the MC402 include its straightforward operation, true hardwire bypass, and durable construction.
