T.WAH (Touch Wah)
You can produce a wah effect with the filter changing in response to
the guitar level.
AUTO WAH
This changes the filtering over a periodic cycle, providing an
automatic wah effect.
OCTAVE
This adds a note one octave lower, creating a richer sound.
* Because of the need to analyze the pitch, chords (two or more sounds
played simultaneously) cannot be played.
Parameter/
Range
Explanation
MODE
Selects the wah mode.
LPF
(Low Pass Filter) This creates a wah effect over a wide fre-
quency range.
BPF
(Band Pass Filter) This creates a wah effect in a narrow fre-
quency range.
POLARITY
Selects the direction in which the filter will change in response to the
input.
UP The frequency of the filter will rise.
DOWN The frequency of the filter will fall.
SENS (Sensitivity)
0–100 Adjusts the sensitivity at which the filter
will change in the direction determined by
the polarity setting.
Higher values will result in a stronger re-
sponse. With a setting of 0, the strength of
picking will have no effect.
FREQ (Frequency)
0–100 Adjusts the center frequency of the Wah ef-
fect.
PEAK
Higher values will produce a stronger tone which emphasizes the
wah effect more.
0–100 Adjusts the way in which the wah effect ap-
plies to the area around the center frequen-
cy. With a value of 50 a standard wah sound
will be produced.
LEVEL
0–100 Adjusts the volume of the effect sound.
DIRECT LEVEL
0–100 Adjusts the volume of the direct sound.

Explanation
MODE
Selects the wah mode.
LPF
(Low Pass Filter) This creates a wah effect over a wide fre-
quency range.
BPF
(Band Pass Filter) This creates a wah effect in a narrow fre-
quency range.
FREQ (Frequency)
0–100 Adjusts the center frequency of the Wah ef-
fect.
PEAK
0–100 Adjusts the amount of wah effect applied in
the range near the reference frequency.
Higher values will produce a stronger tone
which emphasizes the wah effect more.
With a value of 50 a standard wah sound
will be produced.
RATE
0–100,
BPM –BPM
Adjusts the frequency (speed) of the change.
When set to BPM, the value of each parameter will be set according
to the value of the BPM (p. 163) specified for each patch. This makes
it easier to achieve effect sound settings that match the tempo of the
song.
* If, due to the tempo, the time is longer than the range of allowable
settings, it is then synchronized to a period either 1/2 or 1/4 of that
time.
DEPTH
0–100 Adjusts the depth of the effect.
LEVEL
0–100 Adjusts the volume of the effect sound.
DIRECT LEVEL
0–100 Adjusts the volume of the direct sound.
Parameter/
Range
Explanation
RANGE
This selects the register to which the effect is applied.
RANGE1 B1 (corresponds to the sound of an open 7th
string) to E6 (corresponds to the 1st string
played at the 24th fret)
RANGE2 B1 (corresponds to the sound of an open 7th
string) to E5 (corresponds to the 1st string
played at the 12th fret)
RANGE3 B1 (corresponds to the sound of an open 7th
string) to E4 (corresponds to the sound of an
open 1st string)
RANGE4 B1 (corresponds to the sound of an open 7th
string) to E3 (corresponds to the 4th string
played at the 2nd fret)
OCTAVE LEVEL
0–100 Adjusts the volume of the sound one octave
below.
DIRECT LEVEL
0–100 Adjusts the volume of the direct sound.
