Noise Suppressor; Equalizer - Boss GT-1000 Parameter Manual

NOISE SUPPRESSOR 1, 2

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.
Parameter Value Explanation
ON/OFF
OFF, ON Turns this effect on/off.
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 lower setting is appropriate. Adjust this value
until the decay of the guitar sound is as natural as

Value Explanation
Adjusts the tone for the low frequency
-20–+20dB
range.
Adjusts the tone for the high frequency
-20–+20dB
range.
Adjusts the overall volume level of the
-20–+20dB

equalizer.

Specifies the center of the frequency
20.0Hz–16.0kHz range that will be adjusted by the LOW-
MID GAIN.
Adjusts the width of the area affected by
0.5–16 the EQ centered at the LOW-MID FREQ.
Higher values will narrow the area.

Specifies the center of the frequency
20.0Hz–16.0kHz range that will be adjusted by the HIGH-
MID GAIN.
Adjusts the width of the area affected by
0.5–16 the EQ centered at the HIGH-MID FREQ.
Higher values will narrow the area.
Adjusts the low-middle frequency range
-20–+20dB
tone.
This sets the frequency at which the low
FLAT, cut filter begins to take effect. When FLAT
20.0Hz–16.0kHz is selected, the low cut filter will have no
effect.
This sets the frequency at which the high
20.0Hz–16.0kHz cut filter begins to take effect. When FLAT
FLAT is selected, the high cut filter will have
no effect.
