About the

927  
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 “Informationpage.  
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)

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)

A delayed sound is added to the normal guitar sound, producing a thicker tone with a distinctive ambience.  
DLY (delay)

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 mixafter 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.

Recovering Backed Up Data (RECOVER)  
Recovering Backed Up Data to SD Cards (RECOVERY)  
Use this procedure to restore JS-8 data previously backed up on a computer to SD cards.  
You can restore the JS-8 to its status at the time the data was backed up.  
The computer procedures in the following descriptions use Explorer and My Computer with Windows and Finder and other applica-  
tions with the Mac OS.  
1. Connect the computer to the JS-8's USB port by a USB cable.  
2. When the USB SELECT screen appears in the JS-8, select JS-8 SONG LIST EDITOR and press [ENTER].  
3. Copy (drag and drop ) the backed up entire “ROLAND” folder on the computer to the “JS-8” icon (or the “Removable disk (*:)”  
icon) and drop it there (overwriting it).  
"Removable Disk (*:)" may appear instead of the JS-8 icon.  
During the copy, a message may appear on the computer saying that an identical ꢁle exists at the copy destination. If this oc-  
curs, click "Overwrite all" to continue with the copy.  
Recovering (copying) backed up data to an SD card results in the loss of the content of the card prior to the recovery, restoring  
the card with the data at the time the data was backed up.  
Copy the entire ROLAND folder. Copying only portions within the ROLAND folder may render the data unusable as backup data.
