Features

q Stereo output gives your sound greater breadth along with a deep effect that imparts a sense of three-dimensional rotation. q Includes a new ULTRA mode for a more intense flanging effect. q 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. q Includes a MOMENTARY mode, which allows you to apply the flanger effect exactly at the point in a phrase you want. q Also includes a Tap Tempo function that lets you set the RATE to the tempo at which the pedal is pressed.

Panel Description

fig.01

1. AC Adaptor Jack 1 2

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 (PSASeries), 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).

2. CHECK Indicator

This indicator shows whether an effect is ON/OFF, indicates the tempo (TEMPO mode: p. 1112), 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

Panel Description on when you plug into the GUITAR IN or BASS IN jack; the power is turned off when the cable is unplugged. Be sure to disconnect any cord plugged into the GUITAR IN or BASS IN jack when not using this effects device.

6. Pedal Switch

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).
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.

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.

12. MODE Knob

Selects the flanger effect and pedal mode. ULTRA:
Provides a stronger flanger effect than STANDARD.

STANDARD:

Provides a normal flanger effect.

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.

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.

11. RATE Knob

Adjusts the rate of the flanging. The flange effect speeds up as you turn the knob to the right.

MOMENTARY:

The flanger effect is applied only while the BF-3s pedal is depressed. The STANDARD tone is applied, and flanging starts in the low end. * You cannot input the tempo in MOMENTARY mode.

Connections

AC Adaptor BOSS PSA-series (option) OUT 9V DC/200mA Electric Guitar
Bass Guitar Guitar Amplifier (Bass Amplifier)
For monoural use, make the connection to the OUTPUT A (MONO) jack.
* The GUITAR IN jack is given priority.
Connections * Inserting a plug into the GUITAR IN or BASS IN Jack will automatically switch the unit on. * The use of an AC adaptor is recommended as the units power consumption is relatively high. Should you prefer to use batteries, please use the alkaline type. * Noise may be produced if wireless communications devices, such as cell 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. * 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. * If there are batteries 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). * Once the connections have been completed (p. 8), 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. When powering up: Turn on the power to your guitar amp last. When powering down: Turn off the power to your guitar amp first. * Always make sure to have the volume level turned down before switching on power. Even with the volume all the way down, you may still hear some sound when the power is switched on, but this is normal, and does not indicate a malfunction. * When operating on battery power only, the units indicator will become dim when battery power gets too low. Replace the battery as soon as possible.

Troubleshooting

Power wont come on:
q Is the specified adaptor (PSA-series; sold separately) properly connected? Check the connection once more (p. 8).
* Never use any AC adapter other than one specified for use with the BF-3. * 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.
CHECK indicator doesnt light:
q Is the MODE knob set to MOMENTARY? When in MOMENTARY mode, the CHECK indicator light is normally off (the effect is off). The indicator lights (the effect is on) only while the pedal is depressed. The CHECK indicator lights up for several seconds immediately after the power is turned on.
q Is the battery low or dead? Replace with a new battery (p. 14). q Is the guitar connected properly to the GUITAR IN or BASS IN jack? Check the connection once more (p. 8).
* To prevent excess battery drainage, turn the power on without the plug inserted in the GUITAR IN or BASS IN jack. * The battery that was supplied with the unit is for temporary use-intended primarily for testing its operation. For using the unit for more extended periods of time, we recommend the use of alkaline batteries.

No sound / Low volume:

q Is the BF-3 properly connected to your instrument? Check the connection once more (p. 8). q Is the volume turned down on any guitar amp or effects device you have connected? q Are you inputting to both the GUITAR IN and BASS IN jacks? The GUITAR IN jack is given priority. If both jacks are used at the same time, the signal that has been applied at BASS IN will not be heard.
q Could the level of the sound being input be excessive? With some guitars, distortion may be produced. Be careful of your guitar's output level.

Cant input the tempo:

q Is the MODE knob set to MOMENTARY? In MOMENTARY mode, the pedal switch only functions as an effect on/ off switch.

Sound is distorted:

q Is the battery low? As the battery is drained, the CHECK indicator dims, and the BF-3 may start to function incorrectly. Replace with a new battery (p. 14).
Tempo not synchronized with the tempo input:
q Is the MODE knob set to GATE? When synching to GATE, please refer to Relationship Between the Flanger and Gate Effects (p. 13).
