Best wah I've ever used
I've used plenty of Dunlop's, Vox's and Line 6's wahs and the MC-404 is the best by quite some margin. I was between this and a Budda but after reading many reviews of people who once owned them switched to and loved this one, I was pretty much sold. The final nail in the coffin of the Budda for me was they are now manufactured in China I believe and since then, people have had considerably more trouble with them. Vox tends to be too vintage for my taste. Vintage is great in a lot of repects, however it tends to leave one without versatility. Line 6 while always affordable is way too digital sounding for me, but that is what they do after all. Crybabies are ok but to me have little character or versatility. This is something that has made me dislike any wah by them save some of their signature stuff. This wah is manufactured by Dunlop but was designed by Bob Bradshaw, which makes it more of a CAE than a Dunlop. Having the red and yellow settings is like having two wahs in one, both of which are awesome in their own respects. The red has a deep voice that is great, if a bit muddy. I find the yellow to be my favorite due to its funky, well balanced tone. The boost function is an excellent touch, adding a nice helping of overdrive which you can tailor to your sound without creating a bunch of nasty feedback. It also is still technically analog. Even though it has a great modern sound, it manages to do so without sounding digital. The only issue I have had with mine was the poor factory set up, which if you order things online, you are probably used to anyway...The rocker was stiff and sticky at first, so much so it knocked the whole internal mechanism out of place. This was quite scary at first but after opening it up and making a few adjustments and playing with the rocker, it operates and sounds incredibly smooth. I don't find the factory set up to have any bearing on the wah's performance, especially since I made its operation just as I wanted it without having to take it to a tech, so to me it has no effect on the overall score of the pedal itself. I love everything about this wah, from the tone, the ease of operation, right down to the LEDs. As the title states, this is the best I've ever used. If someone knows of a better one, please let me know. Happy wailing!!

Spectacular
This is an spectacular wah. The finish is superb. It sounds awesome! I like that it has a built in boost with a knob to set how much boost you want, for me that is super convenient. Also it has 2 types of wah to choose from, I like the more Slashy one. And less to show how it's working as well if it is engaged. Built like a tank. Great value.

Classic rock sound, however…..
Solid quality wah pedal, awesome classic rock sound Robin Trower, Eric Clapton, etc. All the bells and whistles on this model work fine except I’m a bit disappointed in the boost function. When the boost is on it’s a bit noisy and doesn’t really improve anything about the pedal, it’s reason I bought this model. There are so many different models out there, how do you decide? I wish with all the buttons they put on this thing, they should have put an on/off switch so I don’t have to unplug it when I’m done playing for the night. Disappointed in the lack of a manual that explains things. Other than that it’s a great pedal.

Fantastic Wah. Period.
They thought of all the problems associated with other wahs and went about solving them. The dual fasel is a fantastic idea and in conjunction with the internal trim pots you can really tailor it to your sound. They're not easily accessible but that's not an issue I don't know many people who micro adjust their settings per song. Wanna different taste? switch between fasels. The boost is a nice feature too however it was not a deal maker for me but it is useful and doesn't add very much noise at all.Red Fasel: Nice and creamy and very full sounding. Definitely my favourite. This is what you'd use when playing a bit of HendrixYellow Fasel: Very much the token Dunlop modern wah sound. Think GCB95-F or classic. Focused more towards the highs. The live version of No Quarter by Led Zep is my favourite song to play with this fasel.My biggest problem was that the Allen Key wrench wasn't supplied with my wah but that was solved when I emailed Dunlop for a replacement and the sent me one free of charge. The adjustable pedal was very important to me as I really don't like a sloppy pedal.I've owned the Dunlop Classic w/Fasel and a Bud-wah but I think my search for a wah has ended. Some of those extremely expensive boutiquey wahs may come close or even be a little better than this one however they most definitely won't beat the value of this wah. IMHO it is a wah that is underpriced, yes I can't believe I just said that, the build quality etc is just top notch. Highly recommended.

Best Pedal I own... Electric and acoustic!
I love this pedal! Bought for electric and was curious just how far I could go with it on acoustic... Hours of messing around and several song ideas later, it's worth it. You won't want to play acoustic without it. It's opened up some crazy progressions that you can't really do because they don't usually sound right on guitar.I use both red and yellow inductors equally... It just depends on which way I feel it needs to go. For example, if I feel what I'm playing is climbing up, I'll use the yellow and if I feel what I'm playing coming down/ending, I'll kick it onto the red inductor.
