Versatile wah - great sound

Alexander aus N. 19.02.2014

The features on this wah pedal made want to have one immediately. I used to play Morley wah pedals because of their convenient switch (i.e. step on it and go), but I wasn't quite happy with the sound. With the MXR MC-404 I can actually get the "normal" wah sound which is, at least to my ears, still the best for clean sounds AND I can also have a wah sound that works really well with hi-gain sounds. Since I am using the higain channel on my amp most of the time, I really dig the red setting of the wah. Additionally, the boost switch is another great feature on this pedal (mine is usually on to deliver some extra kick!). I have been playing 20+ gigs with this pedal now and I am very happy with the way it holds up, can't complain about the quality.

The only thing that is bothering me is that is hard to turn off/on the mini switches on the lefthand side when the pedal is on a pedal board. This takes away the versatility in live situations.

This one ranks among the greatest for me, right up there next to the Real McCoy Picture Wah, Fulltone Clyde Deluxe, Xotic Wah & Dunlop Bonamassa Wah. The options make it a killer in the studio and the funkiness on the cleans got me from the get-go.

Unbelievable quality and sounds.

Emilia S. 09.09.2014

As you plug this, you smile. I couldn't believe the difference between this and a "normal" dunlop crybaby. Astonishing difference in the quality of sound. Expecially if you're recording i nstudio, this is like having all the wah options in one box, which makes it really worth the money in a long run. Avoid having other wah until you try this one. The boost knob also colors the sound slightly, but it a way that really makes you smile, again! I also like the fact that I FINALLY have a led to know if the baby is on or off in live situations. Great pedal, worth ALL the money in my opinion, one of the best pedals available on the market today. I would only have put an even bigger led to signal if the pedal is on or off, as it might be confusing initially to discern if the on/off led or if the feasel yellow/red led is on. Apart from this really minor detail, if you're looking for a quality wah which is also a boos and gives you a wider palette of tones, buy it, you won't be disappointed.

great addition to my gear

JJj 27.02.2014

This wah-wah lets you chose between red or yellow Fasel inductor. Difference in sound is very distinct and I like both options. So this is really a killer feature to me.
It also features internally adjustable "Q factor" separately for both coils, but I cannot tell much about that, because I have not tested it thoroughly yet. Certainly it seems like nice thing to have.
Another great thing about this pedal is integrated booster (this is exactly what I needed). It can be easily used like a booster pedal (when it is leaved in down to switch position). But it needs to be mentioned that it colors the tone very much. I personally find it a good thing, but some people might want something neutral. When it is on yellow, the sound is bright, if you switch on in red, it gets darker and thicker. I can notice some difference in low frequency response compared to unboosted amp, but I don't see it as unwanted low frequency roll-off. It just makes my speaker cabinet sound less "boomy".
Few words about quality of the product: "long life CTS potentiometer" became very noisy soon after first use. Sent it back to Thomann for repair under warranty (by the way - I am very happy with the service - got it back quickly). Since then it works fine, but still remains a little noisy. The pedal is otherwise built solidly, replacement parts are available and it shall be easily serviceable..
