1. Changing the orientation of the microphone(s).
2. Relocating microphone(s) at a greater distance from speakers.
3. Lowering volume levels.

About the USB Memory
Connector
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 abso-
lutely 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.
Only USB memory can be connected to the USB memory
connector. Do not connect devices such as a hard disk or
CD-ROM drive.
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 JS-8's Internal Eꢁects
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 Eꢁects
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)
”CHORUS parameter list”(p. 30)
This effect adds reverberation and other spatial effects.

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.
GUITAR (DRY)
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.
With this setting, you can still
monitor the guitar sound with
effects, but the DAW will capture
the sound before effects are ap-
plied.
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 gui-
tar 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 al-
lows 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.

• Is the SD card lock on?
• Does the SD card have too little free space available?
• Are you using an SD card that is known to work with
the JS-8?
No sound
• Is the MASTER LEVEL knob turned down? (p. 6)
• Is the SPEAKER switch set to OFF? (p. 31)
• Are there any songs on the SD card?
• Do you have more than 4,000 songs (including WAV
and MP3 ꢁles)? (p. 28) Delete any songs you don't
need. (p. 31)
Recorded sound is distorted
• The JS-8 only handles up to 2,000 artist, album, and
keyword headings. Delete any unneeded artists,
albums, or keywords. (p. 28)

• Is the SD card completely inserted?
Can’t play MP3/WAV ꢀle
• Have you inserted an SD card that is not supported by
the JS-8?
• Are the MP3 ꢁle's sampling rate and bit rate or the
WAV ꢁle's sampling rate and quantization bit rate sup-
ported by the JS-8? (p. 3)
SD card data corrupted
Corruption of data on SD cards may be caused by the follow-
ing. Reinitialize the SD card.
• Increasing the playback speed or changing the pitch
of MP3s with higher bit rates may not be eꢀective in
playing back these ꢁles. In such cases, convert the
song to JS-8 format. (p. 38)
• Could the power have been turned oꢀ during record-
ing or while the JS-8 was connected via USB to your
computer?
• Did you disconnect the USB cable while the JS-8 was
connected to a computer?
• Did you remove the SD card while the JS-8 was still
turned on?
Can’t set AB REPEAT segment times correctly
• You cannot set the interval between Point A and Point
B to a value less than 0.5 seconds. Increase this inter-
val so that it is at least 0.5. seconds.
• Could the SD card have been subjected to strong
impact?
Problems with USB memory
• You may be unable to properly play back AB REPEAT
segments with MP3s. In such cases, convert the song
to JS-8 format. (p. 38)
