EQUALIZER
OUTPUTRange: 0 ~ 200%
Determines the level of the processed sound.
Settings above 100% are used for boosting the
signal to an appropriate level to compensate for
equalizer adjustments that bring the overall
signal level down.
WAH + EQ (WAH, WEQ)
Wah is a filter sweep effect that, as its name
implies, produces a “wah” type sound. The sweep
of the filter can be made to vary automatically, or
it can be controlled by the input level or with a
connected external foot controller. A separate two-
band parametric equalizer is included after the wah
effect and can be adjusted with the sub parameters.
In Pedal and Touch, the
setting of the pedal or
the level of the guitar
signal (minimum or
maximum) determines
the position of the filter
in the specified range.
Auto uses an LFO (low
frequency oscillator) to
move the center
frequency back and forth
in a cycle as far as the
specified range.
TYPE Settings: Touch Slow (TOUCH SLW),
Touch Fast (TOUCH FST), Auto, Pedal (Wah
Pedal operation only; see page 47).
The Touch settings let you control the Wah effect
by the level of the input signal (or how hard you
play). The filter sweep (or “wah” sound) starts at
the beginning each time it is triggered. Touch
Slow creates a slow single sweep down, while
Touch Fast has a fast single sweep down.
The Auto setting creates a repeating sweep cycle
that runs freely, independent of the input signal;
the speed of this cycle can also be adjusted.
The Pedal setting lets you sweep the filter manu-
ally with a connected foot controller. This setting
is available only when WAH PEDAL operation
has been selected for the external foot controller;
also, Touch Slow, Touch Fast and Auto cannot be
selected when the foot controller has been as-
signed to WAH PEDAL operation. (Refer to the
section “SETTING THE FUNCTION OF THE
EXTERNAL FOOT CONTROLLER — FOOT,”
page 47, for more information on WAH PEDAL
operation.)
SENSE (controlled with the second knob from the
left, when Touch Slow or Touch Fast are se-
lected) — Range: 1 ~ 10
The higher the value, the more sensitive the
trigger of the Wah effect is to low level signals.
Note:The second knob from the left
controls different parameters,
depending on the selected type.
HINT
For best results, when playing a solo or
a line, try setting Sense to a high value;
when performing backing or rhythm
parts, try setting Sense to a low value.
