MXR and Custom Audio Electronics founder Bob Bradshaw—two names that have shaped the tones of the world’s greatest guitarists—join forces to bring you a dynamic new line of pedals. The Boost/Overdrive and Boost pedals are the first offerings in the series produced by MXR, featuring the unique sonic stamp of legendary designer Bob Bradshaw. Since 1980, CAE’s innovative pedal designs were made in limited quantities only for his select clientele. When it was time to bring these pedals to the masses, there was only one name he could trust to deliver the same quality and standards that his customers demand—MXR.

The MC402 Boost/Overdrive offers the combination of a simple dynamic overdrive and an independent clean boost circuit—all in one compact pedal. The overdrive section is truly "classic", adding warmth, sustain and punch, without coloring your sound. It can go from a bluesy, slightly overdriven sound to full-metal crunch with a twist of the gain knob. The MC402 also cleans up nicely when you roll back your guitar volume, making it extremely touch sensitive and responsive to picking dynamics, without becoming thin sounding. The boost circuit alone is a bonus, as it is the exact same circuit CAE has used for years to solve a wide variety of signal conditioning problems in major guitar systems. The MC402's high quality components provide quiet operation and trouble-free interaction with other pedals on your board. In keeping with the CAE tradition, the design is simple and straight forward, with a minimum of controls—only what is necessary to do the job.

  • Dynamic overdrive/distortion.
  • Sensitive and responsive to touch and picking dynamics.
  • Up to +20dB of uncolored clean boost.

Power: Dunlop ECB003 AC Adapter or Single 9-volt battery (not included)

Someone gets it right.


Someone finally gets it right. I know businesses need to make money, but there's nothing wrong with giving users a versatile product that can do more than one thing. This is a great product. Not only is the sound quality fit for a professional, but the price is right. What MXR has done here is create a very responsive overdrive stage that dials in very articulate, gritty distortion (overdrive) but added a great deal of headroom for hard rock saturation and sustain. The boost stage is on a separate button and is separately adjustable. The boost will work independently and WILL boost a clean guitar, a completely different distortion on a chain, or even the amp's distortion. So this is in fact two pedals in one. The effect is versatile, rangy, durable and professional that while maintaing it affordable. This pedal goes from having NO gain to complete hard rock saturation on one knob. The construction is rugged and made to take punishment. The boost is 100% crystal clear. /It is definitely professional quality sound. I use the MC 402 mainly as a saturated full-throttled overdrive and I use the boost to solo. I originally intended to make the box into a second channel for my Fender Blues Junior since that's only a 1 channel amp. The pedal is so versatile that you can do a show on it. Absolutely a must have. The only way this pedal could get any better is if it came with a three band EQ. The tone dial still gives you plenty of control over your sound and the compact design means you'll still have plenty of room left on your board for delays, phases, wah's and other distortion flavors.
