Vintage Clav provides simulations of several classic wah effects, as well as some basic filter types. The name 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. Wah wah pedals are also used extensively with the D6. For information about assigning a controller to the Wah effect, see Vintage Clav Misc parameters.
On/off button: Turn the Wah effect on or off.
Mode pop-up menu: Choose a Wah effect type.
Classic Wah: This setting mimics the sound of a popular wah pedal with a slight peak characteristic.
Retro Wah: This setting mimics the sound of a popular vintage wah pedal.
Modern Wah: This setting mimics the sound of a distortion wah pedal with a constant Q(uality) Factor setting. The Q determines the resonant characteristics. Low Q values affect a wider frequency range, resulting in softer resonances. High Q values affect a narrower frequency range, resulting in more pronounced emphasis.
Opto Wah 1: This setting mimics the sound of a distortion wah pedal with a constant Q(uality) Factor setting.
Opto Wah 2: This setting mimics the sound of a distortion wah pedal with a constant Q(uality) Factor setting.
Resonant LP: In this mode, the Wah works as a resonance-capable lowpass filter. At the minimum pedal position, only low frequencies can pass.
Resonant HP: In this mode, the Wah works as a resonance-capable highpass filter. At the maximum pedal position, only high frequencies can pass.
Peak: In this mode, the Wah works as a peak (bell) filter. Frequencies close to the cutoff frequency are emphasized.
Range knob and field: Set the cutoff frequency of the filter. At the extreme left position, Range limits cutoff modulation to a narrow frequency range. Turn the Range knob to the right to set a wider control range.
Envelope knob and field: Determine the sensitivity of the (filter) envelope to incoming note velocity messages. An auto wah effect is produced by using the integrated envelope follower function, which controls the depth of filter cutoff modulation. In practical terms, this means that the dynamics of your performance directly control the depth of the Wah effect.
