Insert Effect Parameter Functions
Preamp
Adjust the distortion and tone of the guitar sound.
* When all Bass, Middle and Treble are set to “0,” no sound may be
produced depending on the “Type” setting.
On/Off OFF, ON
Turns the preamp effect on/off.
Type
This sets the type of the preamp. The distortion and tone
characteristics of each amp are as shown below:
■ With “COSM GTR AMP,” “COSM COMP GTR,” or
“VO+GT AMP” algorithms
■ With “COSM BASS AMP” or “COSM COMP BSS”
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.
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 GUITAR AMP” 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 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.”
* The sound of each Type is created on the basis that the Gain is set to
“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.
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.
JC-120 The sound of the Roland “JC-120,” a favorite
of pro musicians around the world.
CLEAN The sound of a conventional built-in tube
amp.
CRUNCH Allows you to obtain a crunch effect that
creates a natural distortion.
MATCH A simulation of the latest tube amp widely
used in styles from blues and rock.
VO DRV Allows you to obtain the Liverpool sound of
the 60’s.
BLUES A lead sound with a rich middle ideal for
Blues.
BG LEAD: The sound of a tube amp typical of the late
’70s to ’80s, characterized by a distinctive
mid-range.
MS (1, 2, 1+2) The sound of a large tube amp stack that was
indispensable to the British hard rock of the
70’s, and is used to this day by many hard
rock guitarists.
1 A trebly sound created by using input I of the
guitar amp.
2 A trebly sound created by using input I of the
guitar amp.
1 + 2 The sound of connecting inputs I and II of the
guitar amp in parallel, creating a sound with a
stronger low end than I.
SLDN: A tube amp sound with versatile distortion,
usable in a wide range of styles.
METAL: The sound of a large tube amp, suitable for
heavy metal.
METAL D: A high gain and powerful metal sound.
AC It produces the vintage sound of an early
transistor amp.
AMG It produces the sound of a large double-stack
vacuum tube amp with ultra-lows and a crisp
edge.
