Main Features  
Adopting Roland’s original FFP technology, this highly functional DSP bass amp features 100-watt  
sound output through the newly developed 30 cm (12-inch) coaxial 2-way wide-range speaker.  
The amp is equipped with a total of eight COSM amp model types, including seven of the most  
popular bass amps along with a newly developed SUPER FLAT.  
SUPER FLAT is an original amp type that features a wide-range frequency and faithful response  
suitable for use with upright basses.  
In addition to an easy-to-use 4-band equalizer, this amp features a SHAPE function for even  
greater flexibility in creating sounds and rich sound variation.  
The amp is equipped with a total of three bass effect systems, including COMPRESSION, an EFX  
system with CHORUS, FLANGER, and T-WAH, and basic DELAY/REVERB.  
In addition to RECORDING OUT/PHONES jack with high-quality sound modeling, the CUBE-  
100 BASS is also equipped with professional quality BALANCED OUT, LINE OUT, and TUNER  
OUT, and EXTERNAL SPEAKER jacks. With such expandability, this amp can be used for a wide  
variety of applications, from home recording to live performances.  
FFP (Feed Forward Processing) is system control technology that optimizes the performance of  
the amp, speakers, and cabinet characteristics according to the signals being input, based on the  
results of analyses of the operation and behavior of each section of existing amp systems.  
COSM (Composite Object Sound Modeling) is Roland’s innovative and powerful sound  
modeling technology. COSM analyzes the many factors that make up the original sound, such as  
the electrical and physical characteristics of the original, and then produces a digital model that  
can reproduce the same sound.

IMPORTANT NOTES  
291b  
In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY” on pages 2, 3 and 4,  
please read and observe the following:  
Power Supply  
Maintenance  
401a  
301  
Do not connect this unit to same electrical outlet that is being used by an  
electrical appliance that is controlled by an inverter (such as a refrigerator,  
washing machine, microwave oven, or air conditioner), or that contains a  
motor. Depending on the way in which the electrical appliance is used,  
power supply noise may cause this unit to malfunction or may produce  
audible noise. If it is not practical to use a separate electrical outlet, connect  
a power supply noise filter between this unit and the electrical outlet.  
For everyday cleaning wipe the unit with a soft, dry cloth or one that has  
been slightly dampened with water. To remove stubborn dirt, use a cloth  
impregnated with a mild, non-abrasive detergent. Afterwards, be sure to  
wipe the unit thoroughly with a soft, dry cloth.  
402  
Never use benzine, thinners, alcohol or solvents of any kind, to avoid the  
possibility of discoloration and/or deformation.  
307  
Before connecting this unit to other devices, turn off the power to all units. This  
will help prevent malfunctions and/or damage to speakers or other devices.  
Additional Precautions  
553  
308  
Use a reasonable amount of care when using the unit’s buttons, sliders, or  
other controls; and when using its jacks and connectors. Rough handling  
can lead to malfunctions.  
Although the LEDs are switched off when the POWER switch is switched  
off, this does not mean that the unit has been completely disconnected  
from the source of power. If you need to turn off the power completely,  
first turn off the POWER switch, then unplug the power cord from the  
power outlet. For this reason, the outlet into which you choose to connect  
the power cord’s plug should be one that is within easy reach.  
556  
When connecting / disconnecting all cables, grasp the connector itself—  
never pull on the cable. This way you will avoid causing shorts, or damage  
to the cable’s internal elements.  
557  
A small amount of heat will radiate from the unit during normal operation.  
558a  
Placement  
351  
Using the unit near power amplifiers (or other equipment containing large  
power transformers) may induce hum. To alleviate the problem, change the  
orientation of this unit; or move it farther away from the source of interference.  
To avoid disturbing your neighbors, try to keep the unit’s volume at  
reasonable levels. You may prefer to use headphones, so you do not need to  
be concerned about those around you (especially when it is late at night).  
352a  
559a  
This device may interfere with radio and television reception. Do not use  
this device in the vicinity of such receivers.  
When you need to transport the unit, package it in the box (including  
padding) that it came in, if possible. Otherwise, you will need to use equiv-  
alent packaging materials.  
352b  
Noise may be produced if wireless communications devices, such as cell  
921  
To prevent malfunction and/or damage to speakers or other devices,  
always turn down the volume, and turn off the power on all devices before  
making any connections.  
phones, are operated in the vicinity of this unit. Such noise could occur  
when receiving or initiating a call, or while conversing. Should you  
experience such problems, you should relocate such wireless devices so  
they are at a greater distance from this unit, or switch them off.  
941  
Once the connections have been completed, turn on power to your various  
devices in the order specified. By turning on devices in the wrong order,  
you risk causing malfunction and/or damage to speakers and other  
devices.  
1. Turn on the device connected to the CUBE’s input jack.  
2. Turn on the CUBE.  
354b  
Do not expose the unit to direct sunlight, place it near devices that radiate  
heat, leave it inside an enclosed vehicle, or otherwise subject it to temper-  
ature extremes. Also, do not allow lighting devices that normally are used  
while their light source is very close to the unit (such as a piano light), or  
powerful spotlights to shine upon the same area of the unit for extended  
periods of time. Excessive heat can deform or discolor the unit.  
3. Switch on any equipment connected to the CUBE’s LINE OUT,  
RECORDING OUT/PHONES and BALANCED OUT jacks.  
355b  
When moved from one location to another where the temperature and/or  
Turn off the devices in the reverse order to which they were switched on.  
humidity is very different, water droplets (condensation) may form inside  
the unit. Damage or malfunction may result if you attempt to use the unit  
in this condition. Therefore, before using the unit, you must allow it to  
stand for several hours, until the condensation has completely evaporated.  
Wrap the power cord around the cord hook when trans-porting or storing  
the unit.  
356  
Do not insert hands, fingers, etc, into the openings in the unit. In particular,  
if the unit is to used in households with small children, always provide  
adult supervision to ensure that children keep their hands and feet out of  
these openings.  
Do not allow rubber, vinyl, or similar materials to remain on the unit for  
long periods of time. Such objects can discolor or otherwise harmfully  
affect the finish.  
359  
Do not paste stickers, decals, or the like to this instrument. Peeling such  
matter off the instrument may damage the exterior finish.

Sample Settings  
ALL ROUND (SUPER FLAT)  
An original amp featuring a wide-range frequency response.  
This amp type enables clear reproduction of your instrument’s  
sound. This also makes it perfect when connecting bass  
modeling processors or using sound modules like bass synth.  
In addition, you can exploit the equalizer’s capabilities to  
create the perfect bass sound for any musical genre from rock  
to jazz.  
SHAPE switch: OFF  
FINGER & FRETLESS (BASS 360)  
This bass sound made its appearance in the ’70s.  
This is suited for a Jazz Bass with a rear pickup used. This  
produces a warm, contoured sound when the bass is fingered  
near the rear pickup.  
In addition, using this setting while playing harmonics in  
combination with a chorus and a delay enables sounds  
featuring exquisite reverberation.  
SHAPE switch: OFF  
SLAP BASS (SESSION)  
This setting cuts the midrange for a great slap bass sound.  
Setting the SHAPE switch to ON further boosts the low and  
high ends.  
To get a crisp slap sound, lower the HIGH-MID setting and raise  
the TREBLE. This emphasizes the brightness of the string sound,  
resulting in a slap sound with a lighter pull sound. To get that  
attacking sound used in Rock music, raise the BASS and HIGH-  
MID settings to produce a sound with greater power. You can turn  
the LOW-MID knob to reduce the middle and get a heavy sound  
with superb clarity and distinction.  
SHAPE switch: ON or OFF  
JAZZ WOOD (SUPER FLAT)  
This produces a warm bass sound that is perfect for jazz.  
The tonal quality is perfectly suited for fretless-type basses.  
Slightly raising the BASS and HIGH-MID settings is an  
effective way to fatten the core sound of the fretless bass.  
When using an electric upright bass, turning down the  
TREBLE to adjust the sound creates a sound approximating  
that of a wooden acoustic upright. This also produces a natural  
sound with acoustic upright basses.  
SHAPE switch: ON  
SMOOTH JAZZ (FLIP TOP)  
This is a smooth bass sound, just right for jazz and soul.  
For a thicker, bouncier sound, raise the LOW-MID setting.  
When playing in bigger bands, switching the SHAPE switch to  
ON or turning up the HIGH-MID knob slightly is effective in  
preventing the bass sound from getting buried in the overall  
sound.  
When used with wood basses, setting the SHAPE switch to OFF  
results in a sound resembling that of 60s-style miked recordings.  
Setting SHAPE to ON produces the sound of basses recorded with  
piezo pickups in the ’70s.  
SHAPE switch: ON or OFF

Sample Settings  
Set the VOLUME knob at appropriate volume level.  
FUNK WAH (T.E)  
This setting employs the T-WAH feature for a funky sound  
that responds to the bass touch.  
The wah effect becomes even more prominent with the T.E or  
SESSION amp types, which feature response up to the high-  
frequency range. Use the T-WAH knob to adjust the  
sensitivity. Adjust the T-WAH effect with the knob settings  
according to the output of the connected bass.  
SHAPE switch: OFF  
ROCK RIFF (CONCERT 810)  
This is a fat, powerful standard bass sound.  
Raise the HIGH-MID setting to produce a clear picking sound  
when the bass is picked.  
If you want a fatter low end, set the SHAPE switch to ON.  
Raising the GAIN slightly results in an even fatter sound.  
Applying the FLANGER produces a driving sound that goes  
well with rock music.  
SHAPE switch: ON or OFF  
OVER DRIVE (B MAN)  
This setting gives the distorted sound produced by cranking a  
tube amp up all the way.  
You can set the GAIN position to create a huge range of  
sounds, from light-distortion to deep-distortion overdrive.  
You can then use the equalizer to create a wide range of  
different tones.  
You can get distortion with a fat, undulating sound by raising  
the LOW-MID setting, while turning up the TREBLE and  
HIGH-MID and turning down the BASS works to produce a  
bright distortion sound.  
SHAPE switch: OFF
