MC404 CAE Wah

MXR

collapse expand iconDescription

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.

absolutely smokes your wah pedal.Ha Ha.

Just recieved my wah today and let me tell you this thing sounds awesome. I play an modded Ibanez Prestige through a Mesa Roadster 212. Tried out Clydes,Joe Satch's wah,Q535,and the Wahzoo which I must say is also very awesome. Both are true bypass and true to your tone. I chose the CAE because of the extra features. The boost makes my channel 2 a new found joy to play on as my leads on this channel now sound very soulful and sustainy. It's like I have 2 channels on my channel two. Very nice wakka wakka. Noticeable dual Fasels. Two internal Q's you can easily adjust and dial up boost. This pedal has it all. If I lost this pedal I would buy another one that hour. So,from clean playing with my volume knob rolled backed all the way to the hardest crunching gain I can muster up this thing is the bomb.

Don't Work

I know what you're thinking: everyone else is giving it 5 stars and this guy is only giving it 1 star. Obviously, works for the competition or has issues with Dunlop. Well, I can assure I don't on both accounts. I love Dunlop pedals, especially the MXR models. The reason I'm giving it 1 star is that I couldn't get one that worked. The first one lit up and then died, didn't work for even a second. When I returned it the salesman asked if I wanted a refund, I said, "No, even the best companies are capable of a lemon. I'll get another one because Dunlop is a very good company so I got their one lemon." When I got the second one it worked-ONE TIME!!! The second time I went to use it it too was dead. I will say this it did sound great-for ten minutes! This experience has really soured my opinion of Dunlop pedals; I just can't get myself to trust them again, so I will be returning this one for a refund. I emailed Dunlop with a complaint; I will update this with their response-if I get one.

    I have ordered three of these pedals. Love the sound but, each of them has come with the foot pedal too loose to hold it's position. MF had no solutions other than return and buy another one. A few YouTube videos later and a screw driver, I fixed it. MXR needs to check these better.

    very little tone suck, works in front of amp or in loop. Red facel great with od/distortion. Boost is nice for solos while using wah

  • You can not go wrong with this pedal.

    The MC404 is easily the best Wah Pedal I have ever owned. The sheer amount of control that the pedal affords you is shocking. A true bypass through the effect, two separate inducers that you can adjust through the internals of the pedal, and a massive quickly adjusting boost ripped straight from another boutique pedal. Both of my 404s have done everything I have ever expected of them and more (aside from the first not surviving an accidental drop into a puddle in a parking lot, but that's more a me-issue). If you're in the market for a versatile Wah-Wah I'm telling you: BUY THIS ONE, YOU WILL NOT REGRET IT.

    Nice, standard Crybaby sound, and custom tweaked to suit my style and sound utilizing the dual inductors. Slight noise when using the standard bypass feature. Could be in the chord shielding. To soon to tell. I call it "The Screamin Demon Terry Rahn Signature Model".

  • I would buy this product again! : )
