Chapter 9 Parameters Guide COSM GUITAR
AC Common Parameters
Besides the other COSM AC parameters, the VG-99 also includes the
following shared parameters.
Parameter/
Range
Explanation
EQ (Equalizer)
A four-band equalizer with high and low ranges is provided. The
sound processed by the effect can be boosted by frequency range be-
fore it is output.
EQ SW (Equalizer Switch)
OFF, ON
Turns the EQ effect on/off.
TOTAL GAIN
-12–+12dB
Adjusts the volume before the equalizer.
LOW GAIN
-12–+12dB
Adjusts the low frequency range tone.
HIGH GAIN
-12–+12dB
Adjusts the high frequency range tone.
LOW MID FREQ (Low Middle Frequency)
20Hz–10.0kHz
Specifies the center of the frequency range
that will be adjusted by the LOW MID
GAIN.
LOW MID Q (Low Middle 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.
LOW MID GAIN (Low Middle Gain)
-12–+12dB
Adjusts the low-middle frequency range
tone.
HIGH MID FREQ (High Middle Frequency)
20Hz–10.0kHz
Specifies the center of the frequency range that
will be adjusted by the HIGH MID GAIN.
HIGH MID Q (High Middle 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.
HIGH MID GAIN (High Middle Gain)
-12–+12dB
Adjusts the high-middle frequency range tone.
Parameter/
Range
Explanation
STRING PAN 1st–6th
100:0–100:0
This sets the left/right pan of each string.
* You cannot adjust the STRING PAN
parameter when AC TYPE is set to STEEL.
* The pan effect is cancelled if a monaural effect
or COSM amp is connected after the COSM
GUITAR effect.
STRING LEVEL 1st–6th
0–100 Specifies the output level of each string.
Parameter/
Range
Explanation
MIX LEVEL
COSM GUITAR
0–100
Specifies the level of the COSM GUITAR.
NORMAL PU (Normal Pickup)
0–100
Adjusts the volume of the normal pickup.
Parameter/
Range
Explanation
NS (Noise Suppressor)
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.
SW (Noise Suppressor Switch)
OFF, ON
Turns the NS effect on/off.
THRSH (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 lower setting is appro-
priate. Adjust this value until the decay of
the guitar sound is as natural as possible.
REL (Release)
0–100
Adjusts the amount of time from the point at
which application of the noise suppressor
begins to when the volume is fully attenuat-
ed.
