Product Description

The MC404 CAE Wah was developed by Bob Bradshaw of Custom Audio Electronics and the Cry Baby design team with the goal of creating a highly versatile wah-wah of top-grade components. It features dual Fasel inductors with two distinct voices (high-end emphasis or low to mid resonance), and a built-in MXR MC401 Boost/LineDriver adds even more flexibility. Choose between inductors and turn the boost on or off with the side-mounted kick switches; bright LEDs on each side of the wah indicate operation status. The MC404 boasts a true hardwire bypass, a long-life CTS potentiometer, and internal pots for “Q” and gain adjustments.

Our Verdict

The MC-404 CAE sounds and looks fantastic. A white Custom Audio Electronics logo on the treadle and front of the pedal, as well as a white rubber border on the bottom casing, complement the black pedal. Another useful feature is the battery box on the pedal’s bottom. Instead of unscrewing four rubber feet to remove the pedal’s rear panel, you just take off the cover to gain rapid access to the 9-volt battery.

With so many different wah pedals on the market today, it might be difficult to decide which type is ideal for you. The MC-404 CAE Wah has enough capabilities and variety to meet any player’s wah pedal desires or demands.

Where to Buy

The best place to buy this product has to be Amazon, due to their competitive pricing and fantastic customer service.
