Owner’s Manual AC DC AC & BATTERY POWERED FET
Thank you, and congratulations on your choice of BOSS BF-3 Flanger. Before using this unit, carefully read the sections entitled: “USING THE UNIT SAFELY” and “IMPORTANT NOTES” (separate sheet). These sections provide important information concerning the proper operation of the unit. Additionally, in order to feel assured that you have gained a good grasp of every feature provided by your new unit, this manual should be read in its entirety.
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.
Panel Description 1. AC Adaptor Jack fig.01 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. 3 4 5 6 7 4 * 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.
Panel Description 2. CHECK Indicator 3. OUTPUT A (MONO)/ OUTPUT B Jack 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. 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.
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.
Panel Description 9. RES (resonance) Knob 12. MODE 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. Selects the flanger effect and pedal mode.

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 unit’s 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.
Operating the Unit 2. Select the mode with the MODE knob. fig.05 * When MOMENTARY is selected, the CHECK indicator light goes off, and the effect is switched off.

Setting the RATE by Inputting the Tempo with the Pedal Switch Relationship Between the Flanger and Gate Effects * The gate effect switches on and off 32 times over the period of the flanger effect's rise and fall. * If you want to have the gate working on eighth notes, press the pedal switch at the beginning of the fourth measure of the song you want to have synchronized. fig.
Changing the Battery When the indicator goes dim or no longer lights while an effect is on, it means that the battery is nearly dead and must be replaced. Replace the battery following the steps below. * This device consumes considerable power, so use of the AC adaptor is recommended. When powering the unit with batteries, use alkaline batteries. fig.09 Thumbscrew Pedal Spring Base Battery Snap Cord Coil Spring Guide Bush Hole Battery Snap Battery Housing 9V Battery 14 1.
Troubleshooting Power won’t come on: ● 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. ● Is the battery low or dead? Replace with a new battery (p. 14). ● Is the guitar connected properly to the GUITAR IN or BASS IN jack? Check the connection once more (p. 8).
Troubleshooting No sound / Low volume: ● Is the BF-3 properly connected to your instrument? Check the connection once more (p. 8). ● Is the volume turned down on any guitar amp or effects device you have connected? ● 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.
