This Wah rocks!

I've been looking at wah pedals for a while now. I've tried a vox wah and a regular cry baby but I couldn't​ seem to like either. When I finally tried the mxr wah, I couldn't believe my ears. I bought it right away and now I use it daily on my rig. Thank you sweetwater and thank you Mr. Jenkins for your help!

So many options!

So I have been looking for a new Wah Pedal for awhile. I have been using a CryBaby Wah since 1988. I have alway love the sound but finally the pot started to wear out and it had always taken out a little output from my guitar. So, enter the CAE-MC404. I run guitar to an original DigiTech Whammy to a G-System into my Marshall. It does not color the sound at all. Turn it off and it is a real true bypass. I can't hear the difference running through it. I love how it has 3 different pot adjustment in side. In just an hour of fiddling I have an awesome sound. I love playing through it and I have found great sounds out of both Fasels. It is so versital and then add in a great sound boost that really drives the amp too?? It is perfect.

You name any boutique level wah, and I've probably owned it. I received this New pedal in usual "Sweetwater" fashion (2 days) with the expert assistance from sales engineer, Ron D. I just finished my 3rd "session" in 2 days with it. The first time, yesterday, the wah was honestly "so, so." The second time, last night, I began using the input level knob and the thing turned into the sweetest, most versatile wah that would no doubt, satisfy any tone hound like myself. But this morning (DAY 2) I dialed in/clicked in the best Hendrix wah tones I've ever heard/owned! Phenomenal!! It interacts with no noise with my other true-bypass fx. My rig: '69 NOS Fender Strat, my pedal board, multiple tube Marshall stacks, plus Marshall Hand-wired 2061 with its stock cab. This pedal rules!! I hate admitting this, but this pedal is way under priced. Its more like a $300 to $400 pedal. The MC-404 CAE Wah pedal is like four wahs into one with its switches at the sides/heel area. It's built to last. It's also very appealing to the eyes. Looks meticulously hand-built. Multiple LEDs keep you informed of your settings. Etc... I could go on... But I'm gonna go plug back into it, and create those "otherwordly" sounds... Thank you Dunlop & Sweetwater! PS. I feel lucky to be one of the first to own one of these!!!

Been thru lots of wah's for a long time, love this one because its voiced right for my needs(JCM 900) also its loud enough!!! The boost is a great feature. I last owned a Clyde Deluxe also cool but more Vox sounding.-better for Fender/Country? I considered the EVH (great too) but went with the CAE for the boost. Great for the Money! Can't believe Im finally happy with my wah sound because Im super picky!!!

Amazingly clear Wah!

All I can say bad about this pedal is the charging input, because I have angled cables, and most people won't even have that problem. Easy on/off button press, smooth pedal movement, great boost, LED's are very useful. This wah does not sound nasally at all, and the side buttons are easy to push with your foot (even the boost knob isn't difficult to turn). The yellow/orange mode sound is like a crybaby, and handles the higher frequencies. the other mode is almost the same, but the lower frequencies are brought out a lot more. I haven't even adjusted the inner knobs yet. This is most definitely worth its price.
