BOSS FRV-1 User Guide
The result of a collaboration with Fender®,
the FRV-1 is a compact pedal that uses
COSM technology to faithfully reproduce
the sound of the classic Fender Reverb unit.
(Composite Object Sound Modeling)
Composite Object Sound Modeling—or “COSM” for short—is BOSS/
Roland’s innovative and powerful 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 electrical and physical characteristics—and creates a digital model
that accurately reproduces the original.
Before using this unit, carefully read the sections entitled: “USING THE UNIT SAFELY” and “IMPORTANT NOTES” (supplied on a separate
sheet). These s ections provide important infor mation concerni ng the proper operation of the uni t.
Additionally, in order to feel assured that you have gained a good grasp of every feature provided by your new unit, this manual
shoul d be read in i ts entire ty. The man ual should be saved and kept on hand a s a conveni ent refere nce.
A battery is supplied with the unit. The life of this battery may be limited, however, since its primary purpose was to enable testi ng.
What is the Fender Reverb?
The Fender Reverb was first introduced in 1961. Created many years
before the digital reverbs that are common today, it’s known as a
“spring reverb” because it produces reverberation by using a vacuum
tube circuit to drive a long spring mechanism. Its distinctively warm yet
brilliant sound has been used in thousands of recordings and countless
live performances, earning it the status of “industry standard” among
standalone spring-reverb units.
Extremely versatile and musical, the Fender Reverb sounds great with
vocals and a wide range of instruments. However, its unique sound
characteristics—including the mechanical r esonance of its springs—are
a perfect match for guitar. Surf music guitarists consider its sound to be
indispensable, and it has achieved long-lasting popularity among blues,
country, and rockabilly players as well. The 1963 Fender Reverb model
is particularly revered, and was the basis for the reverb circuit built into
guitar amps such as the TWIN REVERB
®
, which was first introduced that
same year.

AC Adaptor Jack
Accepts connection of an AC Adaptor (PSA series;
optional). By using an AC Adaptor, you can play
without being concerned about how much battery
power you have left.
* If the AC adaptor is connected while power is on, the power
supply is d rawn from the AC adapto r.
* We recommend that you keep batteries installed in the unit
even though you’ll be powering it with the AC adaptor. That
way, you’ll be able to continue a performance even if the cord
of the AC ada ptor gets accidently disconnected from th e unit.
Use only the specied AC adaptor (PSA series), and
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 effect is on.
* If you’re powering the unit with a battery and the CHECK in dicator 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 “C hanging the Battery.”
* The CHECK indicator shows whether the effect is being applied or not. It does
not indicate whether the power to the d evice is on or not.
MIXER Knob
This knob adjusts the balance between the direct sound and
the reverb sound.
Turning it toward the right increases the reverb sound, and
turning it toward the left increases the direct sound.
* When you turn thi s knob all the way to the left, there is no r everb sound.
Pedal Switch
This switch turns the effect on/off.
Thumbscrew
When this screw is loosened, the pedal will open, allowing you to change the battery.
* For instruct ions on changing th e battery, refer to “C hanging the Battery.”
DWELL Knob
This knob determines the character of the reverb sound.
As you turn the knob to the right, both the richness and volume of the
reverb sound increases. At higher settings, the sound takes on a distinctive
“springy” or “twangy” character that’s unique to spring-type reverb units.
* When you turn this knob all the way to the left, there is no reverb sound.
TONE Knob
This knob adjusts the tone of the
reverb sound.
Turning it to the right of center will
make the sound brighter, and turning
it to the left of center will make the
sound warmer.
OUTPUT Jack
Connect this jack to your amp or to the input of another effect unit.
INPUT Jack
This jack accepts signals coming from a guitar or other musical instrument,
or another effects unit.
* The INPUT jack doubles as the power switch. Power to the unit is turned on when you
plug into the INPUT jack; the power is turned off when the cable is unplugged.
To prevent unnecessary battery consumption, be sure to disconnect the plug from the
INPUT jack when not using the effects unit.

FRV-1.
Q
Is the battery low or dead?
Replace with a new battery.
* The battery that is supplied with the unit is for temporary use, intended
.
.
primarily fo r testing the pedal’s operation.
* If you’ll be using the FRV-1 for an extended time, we recommend that
you use an AC adaptor. If you prefer to use a battery, we reco mmend an
alkaline batter y.
* To prevent unne cessary battery cons umption, be sure to disconnect the
plug from th e INPUT jack when not u sing the effects un it.
No sound / Low volume:
Q Is your instrument properly connected to the FRV-1?
Check the connection once more.
Q Is the DWELL knob and/or MIXER knob turned down?
Turning the DWELL knob or MIXER knob toward the le ft will decrease the
amount of reverb sound when the effect is on; if either knob is turned all
the way to the left, there will be no reverb sound. To hear the reverb, turn
the DWELL knob and MI XER knob to the right.
Q Is the volume turned down on any guitar amp or effects device
you have connected?
Check the settings of the connected device.
Q Is the battery low or dead?
Replace with a new battery.
“Springy,” “twangy,” or “drip-like” sounds are heard in
the reverb:
In the original Fender Reverb, these sounds are produced by the
mechanical resonances of the springs. They are apparent as the DWELL
knob is turned up, and also when dynamic, percussive sounds are played
into the unit. These sound characteristics are particularly popular in surf
guit ar music, and are an integral part of the genre.
As with the other characteristics of the Fender Reverb, the FRV-1
faithfully models these resonance sounds. Turning the DWELL knob to
the left will reduce their level and create more of a “room” reverb sound.
