290 Effects
EQ and Filters (EQ/Filter)
11: St. Vintage Wah
(Stereo Vintage/Custom Wah)
This effect simulates the tonal character of a vintage wah pedal.
You can customize the tone and range settings.
a: Shape
This parameter specifies the sweep curve of the wah. It applies to
all control via auto-wah, modulation source, and LFO, and lets
you adjust subtle nuances of the wah effect.
a: Mode
b: Frequency Bottom
b: Frequency Top
c: Resonance Bottom
c: Resonance Top
If Mode=Preset, this simulates a vintage wah pedal. In this case,
internally fixed values are used for Frequency Bottom/Top and
Resonance Bottom/Top, and these settings will be ignored. The
settings for Frequency Bottom/Top and Resonance Bottom/Top
are valid if Mode=Custom.
12: St. Random Filter
(Stereo Random Filter)
This stereo band pass filter uses a step-shape waveform and ran-
dom LFO for modulation. You can create a special effect from
filter oscillation.
