Boss BF-3 Flanger Pedal

BOSS BF-3 Flanger – Iconic Modulation, Expanded for Modern Players

The BOSS BF-3 Flanger carries on the legacy of the legendary BF-2 with a bold update for today’s guitarists and bassists. Delivering the richest, thickest stereo flanging in a compact pedal, the BF-3 adds new creative modes and expanded control, making it one of the most versatile flangers ever produced.

Classic Meets Modern

At its core, the BF-3 offers the unmistakable swirling tones that made the original an industry standard for over 20 years. On top of that, two new modes open the door to entirely new textures. Ultra mode pushes the flanging into deeper, fatter territory, while Gate/Pan mode creates dynamic, futuristic effects with rhythmic slicing and swirling stereo movement.

Creative Control at Your Feet

Whether you want subtle movement or wild modulation, the BF-3 makes it easy. A dedicated Momentary mode gives you instant bursts of flanging when you need it, and tap tempo control lets you lock the modulation rate perfectly to your playing. With independent inputs for guitar and bass, plus full stereo outputs, the BF-3 integrates seamlessly into any rig.
