* The product names mentioned in this document are trademarks
or registered trademarks of their respective owners, and are not
related to Roland Corporation. In this manual, these names are
used because it is the most practical way of describing the sounds
that are simulated using COSM technology.
ACOUSTIC SIM
This is an original amp type that includes an acoustic simulator.
Turns the sounds from your electric guitar into a clear, refined
acoustic guitar sound.
Using this type together with a single coil pickup provides optimum
sound quality. Slightly turning down the equalizer's BASS and
MIDDLE settings is effective if you are using a humbucking pickup.
JC CLEAN
This is a model of Roland's famous JC-120 Jazz Chorus guitar amplifier.
The ultra-clean, ultra-flat sound offers a smooth feel. This becomes more
effective when used in combination with an effects device.
BLACK PANEL
This is modeled on the classic Fender Twin Reverb amplifier. It can
be used in a wide variety of musical styles, from country to blues,
jazz, and rock. It exhibits rich lows and a bright high end.
BRIT COMBO
This is modeled on the VOX AC-30TB. This is the rock amplifier that
created the Liverpool sound of the '60s. It can produce a broad
range of sounds, from clean to overdrive.
CLASSIC STACK
This is modeled on the sound and response of a Marshall JMP1987.
Used extensively in hard rock during the 1970s, this is truly the
perfect amp for the "top rock" guitar sound.
METAL STACK
This is modeled on the PEAVEY EVH5150. This is a high-gain amp
type, so even at low volumes, you can still get heavy distortion and
sustain.
R-FIER STACK
This is modeled on the MESA/Boogie Rectifier. This super-high-gain
amp is capable of producing slash metal, grunge, and a wide range
of other lead sounds.
MIC
Select this when a microphone is connected.
* Please note the following points when using a microphone.
• Feedback could be produced depending on the location of
microphones relative to the unit. This can be remedied by:
1. Changing the orientation of the microphone(s).
2. Relocating microphone(s) at a greater distance
from the unit.
3. Lowering volume levels.
• The sound will be distorted if you turn the GAIN knob up
too high. Set the GAIN knob to as high a value as possible
before the sound distorts to get the best signal-to-noise ratio.
• Use a dynamic microphone. You cannot use a condenser
microphone or a plug-in powered microphone that requires
a power supply.
