About COSM (Composite Object Sound Modeling)
Composite Object Sound Modeling—or “COSM” for short—is Roland’s innovative and pow-
erful technology that’s used to digitally recreate the sound of classic musical instruments and
effects. COSM analyzes the many factors that make up the original sound—including its elec-
trical and physical characteristics—and creates a digital model that accurately reproduces the
original.
A battery is supplied with the unit. The life of this battery may be limited, however, since
its primary purpose is to enable testing.

About the Fender®BASSMAN®
fig.bassman.eps
In 1951, Fender®introduced the first commercially successful elec-
tric bass—the Precision Bass®.
The amp developed along with it was the BASSMAN®.
Originally intended for use only with basses, the rich and powerful
sound of the classic four-input “Narrow Panel” version, quickly
earned it a strong following among guitarists playing blues, rock,
country, etc. Reissued in 1990 the BASSMAN®can still be found at
work on live stages and in studios around the world.
Among the several models in the BASSMAN®series, the 1959
model is especially acclaimed, and its circuitry had a major impact
on the designs of amps from other manufacturers. For many, the
BASSMAN®is the mother of all amps!

1. AC Adaptor Jack
This jack accepts the connection of an AC
adaptor (optionally available BOSS PSA-se-
ries). By using an AC adaptor, you can play
without being concerned about how much
battery power you have left.
* Use only the specified AC adaptor (PSA-
series), and 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.
* If the AC adaptor is connected while power is
on, the power supply is drawn from the AC
adaptor.
* If there is a battery in the unit while an AC
adaptor is being used, the FBM-1 will switch
over to battery-powered operation should the
line voltage be interrupted due to a power
blackout or power cord disconnection.

2. CHECK Indicator
This indicator shows whether the effect is on
or off, and also doubles as the battery check
indicator. The indicator lights when the ef-
fect is on.
* If you’re powering the unit with a battery and
the CHECK indicator goes dim—or doesn’t
light at all—when you try to turn the effect on,
the battery is near depletion and should be
replaced. For instructions on changing the
battery, refer to “Changing the Battery” (p. 12).
* The CHECK indicator shows whether the effect
is being applied or not. It does not indicate
whether the power to the device is on or not.
3. OUTPUT Jack
This output jack is used for connecting to
guitar amps and other effects processors.
4. Pedal Switch
This switch turns the effect on/off.
5. Thumbscrew
When this screw is loosened, the pedal will
open, allowing you to change the battery.
For instructions on changing the battery, re-
fer to “Changing the Battery” (p. 12).
6. INPUT Jack, BRIGHT IN Jack
These jacks are for connecting the output
from an electric guitar or other instrument or
effects device.
Using the BRIGHT IN jack makes the treble
range more prominent.
* These jacks double as power switch. Power to
the FBM-1 is turned on when you plug into
the INPUT/BRIGHT IN jack; the power is
turned off when the cable is unplugged.
When not using the FBM-1, be sure to
disconnect the plug from the INPUT/
BRIGHT IN jack.
* INPUT is disabled when the BRIGHT IN
jack is used.
