Auto Wah parameters
• On/off button: Turn the Auto Wah effect on or off.
• Wah Type 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.
• AutoGain button: Limit the output signal dynamic range. The waheffect can cause the
output level to vary widely. AutoGain compensates for this tendency and keeps the
output signal within a more stable range.
• Relative Qknob and field: Adjust the main filter peak, resulting in a sharper or softer
wah sweep.
• Wah Level knob and field: Set the amount of the wah-filtered signal.
• Depth knob and field: Set the depth of the Auto Wah effect. When set to 0, the
automatic wahfeature is disabled.
• Attack knob and field: Set the time it takes for the wahfilter to fully open.
• Release knob and field: Set the time it takes for the wahfilter to close.
• Range slider and field: Sweep the wahfilter with a MIDI pedal. The two smaller sliders
set the maximum and minimum values of the sweep range.
