The CAE Wah pedal includes two distinct voices (one for high-end brightness or low to mid resonance), and a built-in MXR MC401 Boost/LineDriver to bump up your guitar sound. There is a switch to choose between voices and a convenient side-mounted kickswitch for turning the boost on or off. This Wah has bright LEDs on each side to indicate mode status and also contains a gain knob for integrating dirtier tones. The pedal is powered by either a 9V battery or power adapter. This used model comes with the original box, manual and packaging. There are minor signs of wear from pedal use as well as scratches and wear from foot/sneaker use.
