Volume
OFF, ON
Adjusts the volume and distortion of the amp.
Bass
Adjusts the tone for the low frequency range.
Middle
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
Adjusts the tone for the high frequency range.
Presence
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
Adjusts the overall volume of the preamp.
Bright
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
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.
