James...'s review"Interesting Design"

Dunlop MC404 CAE Wah
Select between a Yellow or Red Fasel Inductor for two distinct tones
Features a custom designed CTS extended life low noise potentiometer
User selectable gain output stage with kick switch and LED indicator
Designed with low noise class 'A' operational amplifiers
Bright LEDs indicate effect status, inductor mode, and boost on or off mode
True bypass
For power, insert a 9-volt battery, plug in an ECB-003 power adapter, or plug into a Dunlop DC Brick multi-power supply 9-volt output

You don't usually see CAE making products with oddball features like this. An inductor switch to change the tone and a side mounted kick switch for the boost. Of course it has true bypass since it's a CAE product. They hold most of their products to a pretty high standard of quality both in the build and spec areas of construction. It's got an internal Q control. Basically most of the features you could want in a wah pedal.

It feels like a solid build. I'm not surprised though. Wah pedals usually don't break on me but at time I've had problems with traction calibration slipping over time. We'll see how this one fares. The sign on top of the pedal is good for live situations where you can't quite see the otherwise dark surface in a dark stage environment. Travel is good. Feels a lot like the equivalent dunlop build.

The inductor is a cool concept. It's a bit like having two wahs in one. One of them is more of a vintage high end focused voicing. The other is a kind of low end modern thing good for solos because it cuts out a lot of the harshness you usually hear.

Other than that it's basically what you would expect. Boost switch works surprisingly well although I really don't use it much. For the price this is a fairly good deal. Great build quality too.

Dunlop MC404 CAE Wah
Listen Voodoo Child or the generic shaft ... or we can do nothing more for you


A breeze, it engages the pedal and it is pressed, creating a connection between his brain and his foot that induces disorderly movements of the right hand.


The sound is very good, there are the characteristics of the Cry Baby (red) and 845 vox (yellow), breath and less, and true bypass in plus.J'ai have the bowl, mine cracks no, do not color the sound and can get roughly anywhere in a string pedal ... although when you have two pedals saturation background ... a little stuck there ca .... should not too nag either!


The custom Audio replaces the crybaby, by dropping its faults and keeping the typical sound of the Dunlop. Passing the yellow phasel, there is the sound of the vox, funkier and less aggressive. I play on a MesaBoogie Road King or a Fender Princeton with any of my guitar (Gibson / Fender / Gretsch / Rickenbacker) Nothing to Report. The boost with the gain setting is handy for his solo peter, really nice, thank you.
Excellent value for money for a pedal that faithfully reproduces the two-wha-wha are best known in the world.

Dunlop MC404 CAE Wah
Everything has been said, only it should be noted that this new version (after 2013 a priori) do not have the same quality as the old one.
To dissociate the old the new, you must return the pedal and watch the inscriptions. If indications (instrument, boost etc. ..) are written horizontally: then this is the oldest and best.
Otherwise, if it is written to the vertical with white rubberized covering just the scriptures then it is new ... Not impressed (see ci_dessous).


Very easy to use. Boost very useful and the choice between 2 fasel is really cool.
However, it should provide space on the pedalboard to gain access to these buttons and do not fit the 48.


The big problems come here.
I bought the new version and made it the next day.
Why? It is not at all clear ... When it is not enabled, you lose a lot of acute frequencies. I JVM410C an amp that is highly crystalline. I found myself with an average amp range in two seconds just by plugging this pedal.

I tried using a buffer more. The difference is less noticeable but still if you are addicted to your clean.
The same for the distortion: you lose a lot of harmonics.

I returned to the store and was able to test the old version in demo. The bypass is much better on the old version. Damage that expo was too damaged ...

Shame ... The effect itself is very good.


I have not tried many models.
The crybaby base is far too gaudy for me.
This, once triggered effect is very good. Too bad it filters both the bypass mode ....

In short, avoid the new version.

Qill's review (This content has been automatically translated from French)

Dunlop MC404 CAE Wah
1 push button for red or yellow Fasel with yellow or red LED
1 push button with blue LED boost
1 button adjustable boost level
1 green LED for activation of the pedal
True Bypass
input power supply or 9V battery


Very weak point of the pedal, after that there are in the chain must play on the battery otherwise it will bring out the best noise / hiss or imcompatibilités (Fuzz, treble booster ...) I n ' happens not to understand is that with the EVH and ZW no problemo ... pedal probably capricious
Otherwise I find it lacks flexibility, the pan is too rigid, it is broken testicle
Last boost it a little signal so we have a little breath


with red Fasel was quite generous, very typical vintage old school with nice bump quite low, it sounds pretty dark, great on clean and the low drive
with such as red but more open less dark yellow Fasel was this bump vintage typed, ideal for drive a little more muscular guy middle gain, the record is less packed
compared to the ZW is with red Fasel, the frequency of the CAE is narrower, the ZW sounds less vintage, more balanced signal with a slightly less eaten one is between the red and yellow Fasel, after I use the ZW in a high gain register, see middle gain
compared to the EVH is less brilliant snapping, the EVH is more expressive, this is now my favorite pedal, vintage certe less but more happening everywhere
The big black dot that's with my Germanium Fuzz where there imcompatibilité sound is chopped and it blows serious with a Silicon Fuzz it goes better


It's a good pedal, the Fasel red / yellow bright side why not but it's my favorite gadget have a simple Wah with a sound and complete, the boost I do not use I already pedals boost ...
Pedal that I have not kept my favorite because it is the heart EVH I find more expressive with this middle comes out great and brighter in a vintage channel after slap ... in a modern channel I keep my ZW
Which inflated me is the lack of flexibility of the plate, the sound a bit dark takes over and imcompatibilité side with other pedal ...

Tina Arkos's review (This content has been automatically translated from French)" It all but crackle knob prohibitive"

Dunlop MC404 CAE Wah
Everything is here: two fasels, side switches, boost +20 db, LEDs indicating fasel, boost and ON / OFF control of the two Q by trimpot.
Level look I love it! In short, a day that started pretty good!


Nothing really, even to resolve internal trimpots.


Whether it's clear or crunch, the wah is not flimsy cardboard and bland but expressive, musical and very organic. After setting the trimpots wouuaahhh is more consistent (factory setting 1 hour for a knob that goes from 10am to 8am, I personally was at 4am on the yellow and the red 8am fasel fasel). Now in sound quality, there is quality and there as I doubt! I read the test AceLeppard speaking defective screws and pops when the switch is activated and there on the two points I confirm!
For screws must be mega watch to not distort the thread and crunches they are present as if the knob was defective. An audible "scccritch" on the chords where only wah rhythm just fart cash atmosphere!
Finally the boost, not personal use to me, since no loss of db is to report the engagement and the crunch or big sound, I use pedals that already boost the sound.


Although initially seduced by his sending wood Hendrix I quickly became disillusioned with the crippling crunches are certainly less audible with big sound but are ineligible especially if we imagine the result with 10K frontage!
Now, I personally research the sound near the first wah made in Italy (cons less) and when you see the pictures on the web (I did not have the chance to have a real Vox 67) circuits of time it is far enough from the PCB machine made of the MC404. This may be the explanation. Damage, however after trying RMC7, and Vox handwired Budda wah, I thought I had dug the Grail, but the evidence must s'rendre you not n'trouverez eternal life with Custom Audio!

AceLeppard's review (This content has been automatically translated from French)" Bump ..."

Dunlop MC404 CAE Wah
Wah wah analog True bybass.

a jack, an output jack.
a green LED indicates whether the wah is active.

An on / off switch and a knob to control the level of boost / line driver integrated Mxr (careful, it can not function independently of the wah, and is only active if the wah is engaged.) A blue LED indicates whether the boost is engaged.

A switch to select fasel (yellow or red). Respective colors of the LEDs indicate which mode is selected. Internal settings (trim pots) for each Q fasel. As usual with the trim pots, it sucks to deal with, and because the outside is already loaded, one wonders why Dunlop did not choose to put them there.

Hardness adjustable pedal keyword.

The whole, although complex, is quite intuitive.


The general configuration is more complex than a standard wah, say 95 Crybaby or Vox.
The manual may be necessary. It is clear, and as mentioned above, the use is fairly intuitive.

Editing sounds is quite easy once all the different settings controlled.

Having set the switches on the sides to boost and fasels is convenient for some that does not put the pedal to a pedalboard already loaded (and of course it was my case).

The stroke of the wah seems larger than a standard crybaby, against it by it's top.


While the boost is effective and transparent. It is very convenient to inflate a solo, fat sound of the wah that may seem a little low for ordinary or from feedback more easily depending on the angle of the pedal to Hendrix.

For me playing much knob, the boost soon proved clenching: the wah up front, so it involves a burst of gain when it is active, and therefore nuances that go by the wayside. Not up to funker gently on his Strat with the knob 2 pending send the ball to Eddie Hazel.

Then talk about fasels: I found myself in the embarrassing situation or yellow was too loud for my gear, 60's very acidic while the red was too dark (more zakk wylde the idea) ... it involves variety, it's not so bad, but it's another headlock, since we get to trim-potter the bowels of the pedal ...


I used a few months then a mishap happened to me.

After removing the rubber feet of the pedal flat to fix my board, I tried to tighten the screws. THREE of them farted half race. I found myself with three screws not unusable. While this manipulation took place smoothly on two standard crybaby in the past, thank you Dunlop install nazes live in your pedals.
So I had to hold the base to the box by wrapping gaffer, before putting the velcro on top. It's very spot for a wah to 200 euros.

And the worst happened: despite repeated blows vacuum, dust has settled in the circuits to produce an unpleasant "crr" when pedal movements. Between boost and these annoying noises, I could say goodbye to the very soft intro, knob down "Dazed and Confused".

All these crap have disgusted me with this custom audio electronics, which is far from being a bad pedal. I returned from my old crybaby on standard and I have more trouble. At least if it loose me as EAC, it will be less expensive to replace.

Finally, I would advise against this Wah Dunlop / CAE for vintage loving guitarists play their knobs and pedals looking for without headaches like me. In my opinion it is intended more as brothers and sisters in Bob Bradshaw of modern guitarists, owners rack running sound banks and want total control over their sound.

The quality report is justified (two pedals in one: wah and boost), but if it was a remake I would look directly at Fulltone or RMC.

iggy25's review (This content has been automatically translated from French)" Extra"

Dunlop MC404 CAE Wah
Wha comprehensive.
2 fasels a boost, a factor Q by setting fasel, true bypass
The boost is adjusted with a knob on the side and Q factors internally.
The boost and change fasel is via a small switch on each side of the wah.
An LED indicates when the effect is engaged, the boost and a type fasel which gives a good live reading of what is switched on or not.


Change fasel and switching the boost is easily and without having to bend. Handy and think to live.
Too bad the Q factor is not externally adjustable ...


Strong point of the pedal.
Each has its fasel interest. The yellow gives a clear but not strident sound. The red gives a dark and creamy his wish.
The boost can be well out of the mix with wha without gorging sound feedback.
All music is very much in its clear that big distortion.

(I owned the basic cry baby for years I always enclenchais with apprehension because really too gaudy. Here I rediscovered the pleasure of using a good wha on funk or wholesale overdrive solos.)


I can only recommend this wha. Music, practical, versatile and complete short no big flaw.

warlus1's review (This content has been automatically translated from French)" Good at all."

Dunlop MC404 CAE Wah
It's been 15 years since I played the guitar and the wah is one of my first effects, so I played so far on a crybaby, the cheapest thing, cb95, something like that.

In short, I wanted a wah quality

Many loving wah sounds of Cantrell and slash, I thought, I'll try the signatures, result:

- The Slash wah good but the distortion built me ​​is useless, therefore, we remove the price of distortion and you end up with a "simple wah" which Q has been slightly modified. Expensive for some, infact.

- The Cantrell: wah very good (but very typical), I would take it when suddenly I saw the custom audio ...

On the left, a fungus to activate the boost (max 20 db)
At right, a fungus to choose the Fasel (yes, this pedal two Fasel)
Right: a large knob (which is handled with the foot) to adjust the boost.

an LED, lights up or not if it activates the boost
an LED light (yellow or red) to show us the Fasel used
an LED lights up when the wah is activated (by pressing forward on the balance of the pedal)

Son (s).
the yellow Fasel
is the sound of the crybaby in all its glory. Compared to the crybaby of the poor (the one without Fasel), the sound is less shrill in the treble but does not justify a price twice as large (it is the same for all Fasel wah).

The red Fasel
I love the sound is quite different, it is no longer ouha wha ... but not easy to explain, say that when the balance is in the bass, the sound is more moilleux similar (relatively speaking) to Cantrell uses the wah in Alice in Chains, In short, it does not sound crybaby, it sounds .... otherwise.

The Boost
It only works when using the wah.
- In the clear: it cruncher (in a good way) the amp, and yes, the volume increases, it appears from other instruments (Group).
- In distortion: for AC, talking about chaining,:
wah-guitar-amp distortion: so that the volume gained by using the boost is literally eaten by the amount of distortion. In other words, the boost does not make us gain volume but the sustain!
disto-wah guitar-amp: there, the boost acts as a clean sound, you win the volume, but the wah after a distortion, it is not my thing (except for playing the RATM)

The pedal
Balance has an axis of rotation shorter than the crybaby of the poor. The latter being well "oiled", the rocker does not keep its position, by taking our foot, it will return to "closed" position.

When opened, there are three "potentiometers" can be modified (by turning left and right) for a Q of each Fasel, a boost for the (contrary to some comments, mine were not glued). Hold positions as a factory setting provides extreme sounds very strange.

a wah sounds great singing with two different and fulfilling their duties.

a boost (useful or not, it depends)

the white border is messy! ! !

Purchased from Sam Ash in Manhattan (NY) for $ 195 ... I like

jielbi's review (This content has been automatically translated from French)

Dunlop MC404 CAE Wah
2fasels analog wah (1 serious rhythm, a treble for solos) all adjustable opening the box with a tiny screwdriver, an adjustable boost

I note 8 / 10 because access to the settings of Fasel is delicate and in fact we settle once and for all and is closed ... it is in fact "adapt" the presets to your hardware &% &%&%&% is a wah not need degrees ...... plus 3 diodes very pretty:

green = wah we
blue = boost it
yellow or red = severe acute Fasel

daltniens aside the blind or hopefully

So 9 / 10


Excellent ....... THE WAH ...... I use a microphone with acoustic electric LR Baggs active ...... so I'm picky about the limitation quality effects so they do not impair the dynamics and timbre of my beloved acoustic ....

I tried lots of other cry baby with the 535 Multi, vox ..... do not have one Fulltone ankle is doing but more expensive


Excellent, wah has ideal buy for those who have a game of finesse and uncompressed (fuzz behind a thoroughly you can put anything ca happen)

a great purchase that I do not regret it ....... now I have to find an overdrive ... it's been a year that I want and I have yet to find a satisfactory (to be defined acoustic) . if you have any ideas


THE wah I expected

zephyrsong's review (This content has been automatically translated from French)

Dunlop MC404 CAE Wah
Wah standard form (cry baby, vox ..) with a boost control and two Fasel that changes the frequency curve of the wah.
Powered by battery or adapter (9v).
4 LEDs: one for activating the effect, both for the choice of Fasel (red or yellow) and for activation of the boost.

The only minor drawback is that the settings of Q Fasel and the gain of the pedal are internal (via tri pot). Anyway once we settled into talking more.


No need to book. It engages the effect through pressure on the pedal (like the vast majority of wah), we chose Fasel and presto, here we go. The choice of Fasel is by the switch of law and that of the boost by the left. The boost is adjustable via the volume pot on the right.


Fasel both provide very good versatility.
The yellow Fasel is typed cry baby, but with adjusting the Q 1 / 3, we get a nice wah, very musical, not at all showy in the highs and no draft in the bass.

Fasel the red when it is darker in offering a deeper wah. With a relatively short delay, we get almost the same sound as the solo John Frusciante Unreachable.

The boost is a real plus on the solos.

It also behaves well in clean when saturated. A delight.

Note that there is no increase in volume when switching effect (boost off), which is a very good point.


I use it for a week. It replaces my ibanez WH10 v2 (switch death). I blamed the latter has difficulty activating effect and the increase in volume when switching. The EAC meets my needs perfectly. It is not about to leave my pedalboard.
