114 Effects
EQ and Filters (EQ/Filter)
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.
13: VOX Wah
This models the legendary VOX V847 and V848 Clyde McCoy
wah pedals. Its distinctive tone, sounding as though it were
wrung from the throat, made this pedal a favorite of many pro
musicians.
14: 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.
a: LFO Phase [degree]
Offsetting the left and right phases alters how modulation is
applied to the left and right channels, creating a swelling affect.
a: LFO Waveform
b: LFO Frequency [Hz]
c: LFO Step Freq [Hz]
When “LFO Waveform” is set to Step-Tri, LFO is a step-shape,
triangle waveform. The “LFO Frequency” parameter sets the
original triangle waveform speed. Changing the “LFO Step Freq”
parameter enables you to adjust the width of the steps.
When “LFO Waveform” is set to Random, the “LFO Step Freq”
parameter uses a random LFO cycle.
