NS (Noise Suppressor)
This effect reduces the noise and hum picked up by bass pickups.
Since it suppresses the noise in synchronization with the envelope of
the bass sound (the way in which the bass sound decays over time),
it has very little effect on the overall sound, and does not harm its the
natural character.
* Please connect the noise suppressor in the signal path prior to the
reverberation type effect. This setup will prevent an unnatural break of
the reverberation effect.
FV (Foot Volume)
This is a volume control effect.
Normally, this is controlled with an expression pedal connected to
the EXP PEDAL jack or one of the FC-300’s EXP pedals.
* When making the settings determining each pedal’s foot volume
operations, refer to “Setting the GK VOLUME Control and
Switch and the Pedal Function (SYSTEM CONTROL
ASSIGN)” (p. 42), “Settings Related to the FC-300” (p. 46).
Parameter/
Range Explanation
NS 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 bass sound is as natural as possible.
* High settings for the threshold parameter
may result in there being no sound when you
play with your bass volume turned down.
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.
DETECT
This controls the noise suppressor based on the volume level for the
point specified in Detect.
INPUT Volume of the COSM bass and normal pick-
up
NS IN (NS Input) Noise suppressor input volume.
Parameter/
Range Explanation
LEVEL
0–100 Adjusts the volume.
VOL CURVE (Volume Curve)
You can select how the actual volume changes relative to the amount
the pedal is pressed.
