The MXR MC404 CAE Wah was designed by Bob Bradshaw of Custom Audio Electronics and the Cry Baby design team to be a highly versatile wah made of top-grade components. It features dual Fasel inductors with two distinct voices (high-end emphasis or low to mid resonance), and a built-in MXR MC401 Boost/LineDriver adds even more flexibility. Choose between inductors and turn the boost on or off with the side-mounted kickswitches; bright LEDs on each side of the wah indicate operation status. The MC404 boasts true hardwire bypass, a long-life CTS potentiometer, and internal pots for Q and gain adjustments.
The CAE Wah allows you to switch between two distinctly-voiced Fasel® Inductors with a built-in Boost/Line Driver circuit, internal Q and gain controls, and bright status LEDs on each side of the pedal.
