Insert effect parameter functions
Section 2
Preamp
This effect is used to adjust the distortion and tone of guitar
sounds.
* When Bass, Middle, and Treble are all set to 0, certain Amp Type
settings may result in no sound being output.
Effect On/Off OFF, ON
Turns the preamp effect on or off.
Amp Type
This sets the type of preamp to be used. The distortion and tone
characteristics of each amp are as shown below:
■
With “COSM COMP GUITAR AMP,” or
“VO+GT.AMP” algorithms
■
With “COSM BASS AMP” or “COSM
COMP BASS AMP” algorithms
Volume 0–100
Adjusts the volume and distortion of the amp.
Bass GUITAR AMP: 0–100, BASS AMP: -100–+100
Adjusts the tone for the low frequency range.
Middle GUITAR AMP: 0–100, BASS AMP:-100–+100
Adjusts the tone for the middle frequency range.
* If you have selected “MATCH” or “VO DRV” as the preamp type, the
middle control will have no effect.
Treble GUITAR AMP: 0-100, BASS AMP: -100–+100
Adjusts the tone for the high frequency range.
Presence 0–100
Adjusts the tone of the ultra-high frequency range.
* This is not displayed when the algorithm is “COSM BASS AMP” or
“COSM COMP BASS AMP.”
* If you have selected “MATCH” or “VO DRV” as the preamp type,
raising the presence will cut the high range (i.e., the value will change
from “0” to “-100”).
Master 0–100
Adjusts the overall volume of the preamp.
Bright OFF, ON
Turns the bright setting on or off.
OFF:
No brightness is added.
ON:
Brightness is added to create a lighter, crisper tone.
* This will not be displayed for certain Amp Type settings.
Gain LOW, MIDDLE, HIGH
Adjusts the distortion generated by the amp, with the level
increasing in sequence for LOW, MIDDLE, and HIGH.
* The sound of each type is created with the assumption that gain is set to
MIDDLE. It is normal, therefore, to use this setting.
