About the Expression Pedal
and Footswitch
Recording and playback on the JS-8 requires an SD card.

About the
Ground Terminal
927
Depending on the circumstances of a particular setup,
you may experience a discomforting sensation, or
perceive that the surface feels gritty to the touch when
you touch this device, microphones connected to it, or
the metal portions of other objects, such as guitars. This
is due to an infinitesimal electrical charge, which is absolutely harmless. However, if you are concerned about this,
connect the ground terminal (see figure) with an external
ground. When the unit is grounded, a slight hum may
occur, depending on the particulars of your installation.
If you are unsure of the connection method, contact the
nearest Roland Service Center, or an authorized Roland
distributor, as listed on the “Information” page.
Unsuitable places for connection
•Water pipes (may result in shock or electrocution)
•Gas pipes (may result in fire or explosion)
•Telephone-line ground or lightning rod
(may be dangerous in the event of lightning)

About the Cover Holder
(indentation)
If you detach the cover of
the USB connector, place

that it won’t be lost.
USB Memory
925
Never insert or remove an SD card while this unit’s power
is on. Doing so may corrupt the unit’s data or the data on
the SD card.
Never connect or disconnect the expression pedal or the
footswitch while this unit’s power is on.
931
About the Security Slot
Carefully insert the SD card all the way in-until it is firmly
in place.
To prevent dust from entering the SD card connector and
to prevent the SD card from being stolen, you should
screw on the connector cover.

About the JS-8's Internal Effects
The trademarks listed in this document are trademarks of their respective owners, which are separate companies from
Roland/BOSS. Those companies are not affiliated with Roland/BOSS and have not licensed or authorized BOSS’s JS-8.
Their marks are used solely to identify the equipment whose sound is simulated.
Internal Effects
With the JS-8, you can use seven effects types simultaneously in a single effects patch, including AMP (amp modeling), FX
(various effects), EQ (equalizer), NS (noise suppressor), DELAY (delay), and REVERB (reverb).
For the FX type, you can select among compressor, distortion, wah, and a wide variety of other effects.
Internal Effects
Models sounds passed through guitar and bass amps.
COSM modeling simulates not just preamp and speaker characteristics, but even miking as well.
You can select from a large number of different amp types.
AMP (amp modeling)
“AMP parameter list”, “MIC TYPE” (p. 24)
Provides a wide variety of effects to choose from, including compressor, distortion, wah, and many others.
FX (effects)
”FX parameter list” (p. 25)
Adjusts the volume levels for different frequencies in the low-frequency to high-frequency ranges.
Low and high midrange settings feature parametric equalization.
EQ (equalizer)
”EQ parameter list” (p. 28)
This effect suppresses noise and hum from the guitar’s pickups.
Since the noise reduction follows the guitar sound’s envelope (the change in volume over time), it has
practically no influence on the guitar sound itself, thus producing a highly natural effect.
NS (noise suppressor)
”NOISE SUPPRESSOR parameter list” (p. 28)
A delayed sound is added to the normal guitar sound, producing a thicker tone with a distinctive ambience.
DLY (delay)
”DELAY parameter list” (p. 29)
This effect adds a subtle frequency modulation, producing a beautiful sound with greater breadth and body.
CHO (chorus)

GUITAR (DRY)
Description
Select this setting when playing
audio from the computer as is.
With this setting, you cannot
play guitar sounds directly
through the the JS-8's speakers.
The only sound that can be
played through the speakers is
audio from the computer.
Select this setting when playing the
guitar while playing back songs with
the computer or when using the
computer to record guitar sounds
without any effects added.
With this setting, you can still
monitor the guitar sound with
effects, but the DAW will capture
the sound before effects are applied.
If you turn the JS-8's power off with USB AUDIO ROUTING set
to RE-AMP or DIRECT OFF, it will be set to DEFAULT the next
time you turn the power on.
What is “Re-Amping?”
This is a technique in which a guitar sound is recorded directly into a DAW without any effects, then played back through
effects later to create a finished guitar sound after the fact. The advantage of re-amping is that, even after recording, you
can use your recorded performance as is to create new sounds. This technique is particularly advantageous if you’ve ever
recorded your guitar with effects added, and then later realized you were unhappy with the results, or found that the guitar gets “lost in the mix” after other parts are added.
With re-amping, you can focus on recording a great performance instead of worrying about getting the perfect effects
sound. Once your performance has been recorded dry, you can then play it back through the JS-8’s effects, adjust the
sound just the way you want it, and then record the result as a new track in the DAW.
When you intend to record a sound dry and re-amp it later, choose GUITAR (DRY) as the JS-8’s USB audio routing. This allows you to monitor the live guitar sound with effects (for inspiration during recording) while sending the dry sound to the
DAW software. To play recorded audio from the DAW through the JS-8’s effects, select RE-AMP as the USB audio routing.

009
Do not excessively twist or
bend the power cord, nor place
heavy objects on it. Doing so
can damage the cord, producing severed elements and short
circuits. Damaged cords are fire
and shock hazards!
010
This unit, either alone or in
combination with an amplifier
and headphones or speakers,
may be capable of producing
sound levels that could cause
permanent hearing loss. Do not
operate for a long period of time
at a high volume level, or at a
level that is uncomfortable. If
you experience any hearing loss
or ringing in the ears, you should
immediately stop using the unit,
and consult an audiologist.
011

WARNING
014
Protect the unit from strong
impact.
(Do not drop it!)
015
Do not force the unit’s powersupply cord to share an outlet
with an unreasonable number
of other devices. Be especially
careful when using extension
cords-the total power used by
all devices you have connected
to the extension cord’s outlet
must never exceed the power
rating (watts/amperes) for the
extension cord. Excessive loads
can cause the insulation on the
cord to heat up and eventually
melt through.
016
Before using the unit in a
foreign country, consult with
your retailer, the nearest Roland
Service Center, or an authorized
Roland distributor, as listed on
the “Information” page.
CAUTION
012b
Be sure to use only the AC
adaptor supplied with the unit.
Also, make sure the line voltage
at the installation matches the
input voltage specified on the
AC adaptor’s body. Other AC
adaptors may use a different
polarity, or be designed for a different voltage, so their use could
result in damage, malfunction,
or electric shock.
Make sure you always have the
unit placed so it is level and sure
to remain stable. Never place it
on stands that could wobble, or
on inclined surfaces.
The  symbol alerts the user to things that must be
carried out. The specific thing that must be done is
indicated by the design contained within the circle. In
the case of the symbol at left, it means that the
power-cord plug must be unplugged from the outlet.
WARNING
Immediately turn the power off,
remove the AC adaptor from the
outlet, and request servicing by
your retailer, the nearest Roland
Service Center, or an authorized
Roland distributor, as listed on
the “Information” page when:
• The AC adaptor, the powersupply cord, or the plug has
been damaged; or
• If smoke or unusual odor occurs
• Objects have fallen into, or
liquid has been spilled onto
the unit; or
• The unit has been exposed to
rain (or otherwise has become
wet); or
• The unit does not appear to
operate normally or exhibits
a marked change in performance.
007
The
symbol alerts the user to items that must never
be carried out (are forbidden). The specific thing that
must not be done is indicated by the design contained
within the circle. In the case of the symbol at left, it
means that the unit must never be disassembled.
In households with small children, an adult should provide
supervision until the child is
capable of following all the rules
essential for the safe operation
of the unit.
101b
The unit and the AC adaptor
should be located so their
location or position does not
interfere with their proper ventilation.
102c
Always grasp only the plug on
the AC adaptor cord when plugging into, or unplugging from,
an outlet or this unit.
103b
At regular intervals, you should
unplug the AC adaptor and
clean it by using a dry cloth to
wipe all dust and other accumulations away from its prongs.
Also, disconnect the power plug
from the power outlet whenever
the unit is to remain unused for
an extended period of time. Any
accumulation of dust between
the power plug and the power
outlet can result in poor insulation and lead to fire.
CAUTION
104
Try to prevent cords and cables
from becoming entangled. Also,
all cords and cables should be
placed so they are out of the
reach of children.
106
Never climb on top of, nor place
heavy objects on the unit.
107c
Never handle the AC adaptor or
its plugs with wet hands when
plugging into, or unplugging
from, an outlet or this unit.
108b
Before moving the unit, disconnect the AC adaptor and all
cords coming from external
devices.
109b
Before cleaning the unit, turn off
the power and unplug the AC
adaptor from the outlet (p. 4).
