This wah cries with versatility.

Bob Bradshaw of Custom Audio Electronics designed the MXR MC-404 CAE Dual Inductor Wah Pedal with the Cry Baby design team to create a highly versatile wah-wah with top-grade components. The MC404 CAE Wah features dual Fasel inductors with 2 distinct voices (high-end emphasis or low-to-mid resonance), and a built-in MXR MC-401 Boost/LineDriver that 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 CAE Wah boasts true hardwire bypass, a long-life CTS potentiometer, and internal pots for the Q control-which varies the intensity of the wah effect-and gain adjustments. You get the high performance and quality that you expect from Dunlop, the world leader in wah-wah technology.

Bob Bradshaw has been one of the world's foremost designers of custom guitar pedal boards and effects systems for many of rock's most influential guitarists for 3 decades. And for just as long, MXR and Cry Baby have been synonymous with the effects pedal innovations that have shaped the tone of modern electric guitar playing. So it was only natural for them all to join forces to create a dynamic line of pedals offering the ultimate in tone, functionality and road-worthy dependability. Since 1980, CAE's groundbreaking pedal designs were made in limited quantities only for a select clientele of world-class guitarists. But now these very same devices and circuits are available to all.

    Comments about MXR MC404 CAE Dual Inductor Wah Guitar Effects Pedal:

    This wah is one of the best and arguably the most versatile out there. It replaced a Bad Horsie 2 on my pedalboard. With the push of a button (w/ your foot btw) the wah will go from classic crybaby treble (but with more body tone wise) to a throaty mid-range voice that is awesome for overdriven or distortion lead work- it blends with your tone beautifully- not hampering your harmonic sound structure. I use mine first in the chain and it excels in hard rock and also for reggae applications. I have not had to adjust internal trim pots yet but the option is there if yo need to fine tune either or both voicings. Finally, the pedal has a boost if you need it!
    Finding the right wah is not easy, give this one a try. You will not be disappointed.
