Boss BF-3 Flanger Pedal

The world's best known compact pedal manufacturer



Probably the most versatile stomp box flanger you can buy. You can go from very subtle, phaser-like effects to full on jet engine in the twist of a few knobs - the BF3 is certainly no one trick pony! The BF3 improves on the legacy of the celebrated BF-2 with new ultra, gate and pan modes which can create great stereo effects or choppy "slicer" effects.  The BF-3 is built for bassists and guitarists with inputs for each. But why not try your keyboard through it too?!

As you probably know, Boss pedals have a reputation for being built like brick outhouses! You can be pretty sure that however much you drop it, kick it, throw it and jump on it, it will still come back for more punishment! These pedals constantly survive the rigors of rock 'n' roll touring, and that's why they're seen at the feet of top touring pros everywhere. Reliability really can be affordable to all, and Boss are so sure that their compact stomps will last that they cover them with a full five year warranty.

Here's what Boss say about the BF3

Building on the 20-year legacy of the famous BOSS BF-2, the new BF-3 flanger pedal gives guitarists and bassists an updated version of the classic BOSS flanger with the thickest stereo flanging sounds ever. Two new modes (Ultra and Gate/Pan) create stereo flanging with incredible depth--even Slicer-type effects and sounds that seem to "swirl" around the listener. An instant classic.
