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 type, the middle
control will have no effect.
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.
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”).
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.
Turns the bright setting on/off.
OFF:
Bright is not used.
ON:
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” and “HIGH.”
increase for settings of “LOW,” “MIDDLE” and “HIGH.”
*
The sound of each Type is created on the basis that the Gain is set to
“MIDDLE.” So, normally set it to “MIDDLE.”
“MIDDLE.” So, normally set it to “MIDDLE.”
Ring Modulator
This creates a bell-like sound by ring-modulating the guitar sound
with the signal from the internal oscillator. The sound will be
unmusical and lack distinctive pitches.
with the signal from the internal oscillator. The sound will be
unmusical and lack distinctive pitches.
On/Off
OFF, ON
This parameter turns the ring modulator effect on/off.
Frequency
0–100
This adjusts the frequency of the internal oscillator.
Fx Level
0–100
Adjusts the volume of the effect sound.
Dir Level
0–100
Adjust the volume of the direct sound.
Slow Attack
This produces a volume-swell effect (“violin-like” sound).
*
This effect can be used in the “COSM GTR AMP” algorithm when
the MODULATION “Type” parameter is set to “SLOW ATCK.”
the MODULATION “Type” parameter is set to “SLOW ATCK.”
On/Off
OFF, ON
This parameter turns the slow attack effect on/off.
RiseTme
10–2000 ms
This adjusts the time needed for the volume to reach its maximum
from the moment you begin picking.
from the moment you begin picking.
Level
0–100
Adjust the volume of the slow attack sound.
AC
It produces the vintage sound of an early
transistor amp.
transistor amp.
AMG
It produces the sound of a large double-stack
vacuum tube amp with ultra-lows and a crisp
edge.
