■
With “COSM BASS AMP” or “COSM

Volume 0 – 100
Adjusts the volume and distortion of the amp.
Bass

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 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
This can be selected in the “COSM GTR AMP,” “COSM
COMP GTR,” or the “VO+GT.AMP” algorithm.
Adjusts the tone for the ultra high frequency range.
* If you have selected “MATCH” or “VO DRV” as the type,
raising presence will cut the high range (the value will
change from “0” to “-100”).
Master 0 – 100
Adjusts the volume of the entire preamp.
Bright OFF, ON
(with JC-120, CLEAN, CRUNCH, BLUES, BG LEAD, AC,
AMG)
Turns the bright setting on/off.
OFF :

Bright is switched on to create a lighter and crisper tone.
Gain LOW, MIDDLE, HIGH
Adjusts the distortion of the amp. Distortion will
successively increase for settings of “LOW,” “MIDDLE”

* The sound of each Type is created on the basis that the Gain
is set to “MIDDLE.” So, normally set it to “MIDDLE.”
