On/Off (Effect On/Off)

Switches the 3-band parametric EQ effect on and off.

*The following parameters affect the Lo, Mid, and High EQ together.

Q

The range is narrowed as the value is increased. This adjusts the equalizer bandwidth (the range of frequencies to which the equalizer is applied). The bandwidth is narrowed as the value is increased, resulting in a more precise (“notched”) equalization. Use higher Q settings to affect specific frequencies and give the tone particular qualities. Conversely, the bandwidth becomes broader as the value is lowered. Use lower Q settings when you want to adjust the overall low end or high end and change the overall tone.

Freq (Frequency)

Adjusts the ED’s center frequency (for the range affected). The frequency (upper range) increases as the value is raised.

Gain

Adjusts the volume level for the equalizer adjusted with the Q and FREQ settings above. The volume level for the frequency range is boosted more as the knob is turned further to the right of center; turning the knob to the left of the center position cuts those frequencies.

Level

Adjusts the overall volume level of the 3-band equalizer. The volume level is boosted more as the knob is turned further to the right of center; turning the knob to the left of the center position cuts those frequencies.

WAH

The wah effect creates a unique tone by changing the frequency response of a filter.

With WAH, you can select the type to be used from the following.

•Pedal Wah

•Touch Wah
