Built into the MC-404 CAE wah, you've got MXR's famous MC-401 Boost/LineDriver, which makes this pedal even more versatile. What's more, the MC-404 CAE sports dual Fasel inductors with two distinct voices, so you can switch from high-end emphasis to low/mid resonance.There are also internal pots for "Q" and gain adjustments on the Dunlop MC-404 CAE wah.
