MXR joined forces with Custom Audio Electronics founder Bob Bradshaw to bring you the MC401 CAE boost/line drive effects pedal. It cleans up nicely when you roll back your guitar volume, making it extremely responsive to picking dynamics without thinning your tone. High-quality components provide quiet operation and trouble-free interaction with other pedals on your board. The MC401's circuit design has been used for years by CAE in the world's best guitarist's rigs to remedy these problems and rejuvenate the sparkle, punch and brilliance that can be lost. It can also be used as an ultraclean boost (up to +20dB) for solos or to drive effects for more dynamics and sensitivity.

Custom Audio Electronics has made limited quantities of pedals for select clientele since 1980, and has now teamed up with MXR to bring these MC401 pedals to the masses.
