The Dunlop MC-404 CAE wah is a total funk machine. The Dunlop MC-404 CAE wah is a total funk machine. No, that's not a misprint - it's actually worth saying it twice. Why? because the Dunlop MC-404 CAE wah gives you twice the über-funky wah as the next wah pedal. You see, inside this baby's two totally different wah circuits. They're both top-quality, made from only the best Fasel inductors - no "good and better" thing going on here. The Boost setting takes the high road, adding spunk and snap to your tone - perfect for cheeky funk and jazzy popping lines. The LineDiver setting goes for the below-the-belt low/mid resonance that's a little sassier, which is killer for classic rock. Plus, you can fine tune the Q of either setting, so you get to dial in your own flavor. See, the Dunlop MC-404 CAE isn't you typical wah pedal... it's a wah wah pedal.The Two switches on the pedal help control and change the wah tone. One switch lets you choose between the two distinct wah voices, either “Yellow Fasel” (Deep wah tone) or “Red Fasel”(Classic Cry Baby tone). The other switch simply turns the MXR boost on and off. There’s no guessing game in knowing what switches are on or off, since bright LED’s on each side of the Wah indicate your operation status. Also, your foot easily controls the small kickswitches on either side of the pedal, as well as the Boost volume control, so there’s no bending over to adjust anything.
