Features
●
Stereo output gives your sound greater breadth along with a deep effect that imparts
a sense of three-dimensional rotation.
●
Includes a new “ULTRA” mode for a more intense flanging effect.
●
Also features a “GATE/PAN” mode. When outputting in mono, a slicer effect is added to the flanging sound, resulting in a “gate flanger” effect; and when using stereo
output, you get a flanging effect that is panned three-dimensionally across the sound
field.
●
Includes a “MOMENTARY” mode, which allows you to apply the flanger effect exactly at the point in a phrase you want.
●
Also includes a “Tap Tempo” function that lets you set the RATE to the tempo at
which the pedal is pressed.

1. AC Adaptor Jack
Accepts connection of an AC Adaptor (optionally available BOSS PSA-Series). 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.
* As soon as you connect the AC adaptor, the
unit is turned on.
* If there is battery in the unit while an AC
adaptor is being used, normal operation will
continue should the line voltage be interrupted
(power blackout or power cord disconnection).
Panel Description
2. CHECK Indicator
This indicator shows whether an effect is
ON/OFF, indicates the tempo (TEMPO
mode: p. 11–12), and also doubles as the
Battery Check indicator.
The indicator lights when an effect is ON.
* If this indicator goes dim or no longer lights
while an effect is ON or while the BF-3 is in
TEMPO mode, the battery is near exhaustion
and should be replaced immediately. For
instructions on changing the batteries, refer
to “Changing the Battery” (p. 14).
* The CHECK indicator shows whether the
effect is being applied or not, and is used to
indicate other effects. It does not indicate
whether the power to the device is on or not.
3.
OUTPUT A (MONO)/ OUTPUT B Jack
The output jacks are used to connect the
unit to an amplifier or another effects unit.
For monaural use, make the connection to
the OUTPUT A (MONO) jack.
4. GUITAR IN Jack
This jack accepts input signals (coming
from a guitar, some other musical instrument, or another effects unit).
5. BASS IN Jack
This jack accepts input signal coming from
a bass guitar.
* BASS IN is disabled when the GUITAR IN
jack is used.
* When running the unit on battery power, the
GUITAR IN and BASS IN jacks double as
power switches. Power to the unit is turned

on when you plug into the GUITAR IN or

Used for switching effects on/off, and for
inputting the tempo.
* You cannot input the tempo in MOMENTARY
mode.
7. Thumbscrew
When this screw is loosened, the pedal
will open, allowing you to change the battery.
* For instructions on changing the batteries,
refer to “Changing the Battery” (p. 14).

8. MANUAL Knob
Adjusts the center frequency to which the
effect is applied.
The range is raised as you turn the knob to
the right (clockwise).
* The settings range varies with the selected
mode, as well as when an instrument is
connected to BASS IN.
Panel Description
9. RES (resonance) Knob
Adjusts the amount of resonance (feedback). The more the knob is turned to the
right, the more the flanger sound is emphasized, and the stronger the characteristic effect in the sound becomes.
10. DEPTH Knob
Adjusts the sweep depth. The effect deepens as you turn the knob to the right.
* The MANUAL knob has no function when
this knob is turned completely clockwise.
11. RATE Knob
Adjusts the rate of the flanging. The flange
effect speeds up as you turn the knob to
the right.
12. MODE Knob
Selects the flanger effect and pedal mode.
ULTRA:
Provides a stronger flanger effect than
STANDARD.
STANDARD:
Provides a normal flanger effect.
GATE/PAN:
When playing in mono, this creates radical
changes in the output volume.When playing
in stereo, this alternately pans the output to
the left and right, resulting in a flanger effect
that imparts a sense of rotation or spinning.
MOMENTARY:
The flanger effect is applied only while
the BF-3’s pedal is depressed. The STANDARD tone is applied, and flanging starts
in the low end.
* You cannot input the tempo in MOMENTARY
mode.
