EFFECT
T. WAH
You can produce a wah effect with the filter changing in response
to the bass level.
Parameter Value Explanation
MODE
Selects the wah mode.
LPF
Low pass filter. This creates a wah effect over a wide
frequency range.
BPF
Band pass filter. This creates a wah effect in a narrow
frequency range.
POLARITY
Selects the direction in which the filter will change in response to
the input.
DOWN The frequency of the filter will fall.
UP The frequency of the filter will rise.
SENS 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 response. With
a setting of 0, the strength of picking will have no
effect.
FREQ 0–100 Adjusts the center frequency of the Wah effect.
PEAK
0–100
Adjusts the way in which the wah effect applies to
the area around the center 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.
E.LEVEL 0–100 Adjusts the volume of the effect sound.
D.LEVEL
0–100 Adjusts the volume of the direct sound.
GRAPHIC EQ
This adjusts the tone as a equalizer. You can adjust the tone
character in seven bands.
Parameter Value
40Hz
-20–+20 dB
100Hz
250Hz
500Hz
1kHz
2.5kHz
8kHz
LEVEL
-20–+20 dB
PARAMETRIC EQ
Adjusts the tonal quality. You can adjust the tone character in four
bands.
Parameter Value Explanation
LOW GAIN -20–+20 dB
Adjusts the tone for the low frequency
range.
HIGH GAIN -20–+20 dB
Adjusts the tone for the high frequency
range.
LEVEL
-20–+20 dB
Adjusts the overall volume level of the
equalizer.
LM FREQ (LOW-MID
FREQUENCY)
20 Hz–10.0 kHz
Specifies the center of the frequency
range that will be adjusted by the LOW-
MID GAIN.
LM Q
(LOW-MID Q)
0.5–16
Adjusts the width of the area affected by
the EQ centered at the LOW-MID FREQ.
Higher values will narrow the area.
LM GAIN
(LOW-MID GAIN)
-20–+20 dB
Adjusts the low-middle frequency range
tone.
HM FREQ
(HIGH-MID
FREQUENCY)
20 Hz–10.0 kHz
Specifies the center of the frequency
range that will be adjusted by the HIGH-
MID GAIN.
Parameter Value Explanation
HM Q (HIGH-MID Q) 0.5–16
Adjusts the width of the area affected by
the EQ centered at the HIGH-MID FREQ.
Higher values will narrow the area.
HM GAIN
(HIGH-MID GAIN)
-20–+20 dB
Adjusts the low-middle frequency range
tone.
ENHANCER
This is an effect that clarifies the contour of the input sound by
emphasizing the attack of the sound following changes in the
input level.
Parameter Value Explanation
SENS 0–100
This adjusts the Enhancer sensitivity. The
more the value is increased, the more
softly you can play and still have the
effect applied.
LOW 0–100
Adjusts the enhancer volume for the low
frequency range.
HIGH 0–100
Adjusts the enhancer volume for the
high frequency range.
LOW FREQ 31.5Hz–125Hz
Sets the low frequency range for the
enhanced sound.
HIGH FREQ 800Hz–8.00kHz
Sets the high frequency range for the
enhanced sound.
TONE MODIFY
This changes the tone of the connected bass.
Parameter Value Explanation
TYPE
Selects the type of tone modification.
FAT
Fat tone with boosted mid range.
PRESENCE
Bright tone with boosted high-mid
range.
MILD Mild tone with the high end cut back.
TIGHT Tone with the low frequencies cut.
ENHANCE Tone with the high frequencies boosted.
RESO 1–3
(RESONATOR 1–3)
This produces a tone with greater power
and punch by adding resonance in the
low-frequency range and midrange.
LOW
-50–+50
Adjusts the tone for the low frequency
range.
HIGH
-50–+50
Adjusts the tone for the high frequency
range.
LEVEL 0–100 Adjusts the volume of the effect sound.
RESONANCE 0–100
This adjusts the strength of the low-end
and midrange resonance when TYPE is
set to RESO 1, 2, or 3.
