Logic Pro Vintage Clav Wah effect
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 Logic Pro Vintage Clav Misc parameters.
Waheffect 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.
