Using Insert Effects
This adjusts the tone as a equalizer. A parametric type is
adopted for the high-middle and low-middle range. This effect reduces the noise and hum picked up by guitar
pickups. Since it suppresses the noise in synchronization
with the envelope of the guitar sound (the way in which the
guitar sound decays over time), it has very little effect on
the guitar sound, and does not harm the natural character of
the sound.
EQUALIZER
Parameter/
Range
Explanation
ON/OFF
OFF, ON Turns the EQUALIZER effect on/off.
LOW CUT (Low Cut Filter)
FLAT,
55Hz–800Hz
This sets the frequency at which the low cut
filter begins to take effect. When “FLAT” is
selected, the low cut filter will have no ef-
fect.
LOW GAIN
-20–+20dB Adjusts the low frequency range tone.
LOW-MID F (Low Middle Frequency)
20.0Hz–
10.0kHz Specifies the center of the frequency range
that will be adjusted by the LO-MID G.
LOW-MID Q (Low Middle Q)
0.5–16
Adjusts the width of the area affected by
the EQ centered at the LO-MID F.
Higher values will narrow the area.
LOW-MID G (Low Middle Gain)
-20–+20dB
Adjusts the low-middle frequency range
tone.
HI-MID F (High Middle Frequency)
20.0Hz–
10.0kHz Specifies the center of the frequency range
that will be adjusted by the HI-MID G.
HI-MID Q (High Middle Q)
0.5–16
Adjusts the width of the area affected by
the EQ centered at the HI-MID F.
Higher values will narrow the area.
HI-MID G (High Middle Gain)
-20–+20dB
Adjusts the high-middle frequency range
tone.
HIGH GAIN
-20–+20dB Adjusts the high frequency range tone.
HIGH CUT (High Cut Filter)
700Hz–
11.0kHz,
FLAT
This sets the frequency at which the high
cut filter begins to take effect. When
“FLAT” is selected, the high cut filter will
have no effect.
LEVEL
-20–+20dB
Adjusts the overall volume level of the
equalizer.
NOISE SUPPRESSOR
Parameter/
Range
Explanation
ON/OFF
OFF, ON
Turns the NOISE SUPPRESSOR effect on/
off.
THRESHOLD
0–100
Adjust this parameter as appropriate for
the volume of the noise.
If the noise level is high, a higher setting is
appropriate. If the noise level is low, a low-
er setting is appropriate. Adjust this value
until the decay of the guitar sound is as nat-
ural as possible.
* High settings for the threshold parameter
may result in there being no sound when
you play with your guitar volume turned
down.
RELEASE
0–100
Adjusts the time from when the noise sup-
pressor begins to function until the noise
level reaches “0.”
