Using the EVB3’s Integrated Wah Wah
The name Wah Wah comes from the sound it produces. It has been a popular effect
(usually a pedal effect) with electric guitarists since the days of Jimi Hendrix. The pedal
controls the cutoff frequency of a bandpass, lowpass, or—less commonly—highpass
filter. The wah wah pedal is also used extensively with the Hammond organ.
Mode pop-up menu: Use to enable or disable the Wah Wah effect. If you choose Off,
the effect is disabled. There are six different filter types available:
ResoLP: (Resonating Lowpass Filter): In this mode, the Wah Wah will work as a
resonance-capable lowpass filter. At the minimum pedal position, only low frequencies
can pass.
ResoHP: (Resonating Highpass Filter): In this mode, the Wah Wah will work as a
resonance-capable highpass filter. At the maximum pedal position, only high
frequencies can pass.
Peak: In this mode, the Wah Wah will work as a peak (bell) filter. Frequencies close
to the cutoff frequency will be emphasized.
CryB: This setting mimics the sound of a famous wah wah pedal.
Morl: This setting mimics the sound of a popular wah pedal with a slight peak
characteristic.
Morl2: This setting mimics the sound of a popular distortion wah pedal. It has a
constant Q (quality) Factor setting.
CC pop-up menu: Use to assign a MIDI controller to the Wah Wah effect. See MIDI Control
of the EVB3 Wah Wah Effect.
Range knob: Controls the sensitivity of the Wah Wah effect to incoming MIDI controller
data. See MIDI Control of the EVB3 Wah Wah Effect below.
Bite knob: Boosts the signal around the cutoff frequency. The Bite parameter is effectively
a filter resonance parameter, so high values will make the Wah Wah sound more
aggressive.
