Information
MXR
The MC-404 CAE Wah was developed by Bob Bradshaw of Custom Audio Electronics and the Crybaby design team with the goal of creating a highly versatile wah-wah 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 MC-401 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 MC-404 boasts true hardwire bypass, a long-life CTS potentiometer, and internal pots for "Q" and gain adjustments—high performance and quality that you can only expect from Dunlop, the world leader in wah-wah technology.
