BOSS BF-3 Flanger Pedal

Building on over two decades of innovation, the BOSS BF-3 Flanger continues the legacy of the legendary BOSS BF-2, offering the most powerful and versatile flanging tones ever produced in a compact pedal. Designed for guitarists and bassists, the BF-3 expands the classic BOSS flanger sound with new stereo modes, richer depth, and incredible tonal movement.

From subtle modulation to swirling stereo effects that move around the listener, the BF-3 delivers the thickest, most dynamic flanging sounds available—making it a true modern classic.

Classic Flanging, Modern Power

The BF-3 offers everything players loved about the original BF-2 and more. With advanced stereo processing and new effect modes, it delivers greater depth, control, and definition than ever before.

  • Updated evolution of the classic BOSS BF-2

  • Ultra mode for deep, immersive flanging tones

  • Gate/Pan mode for dynamic, rhythmic effects and stereo movement

  • Lush, smooth modulation that works for any style

Dedicated Inputs for Guitar and Bass

Unlike many modulation pedals, the BF-3 features dedicated input paths for both guitar and bass, ensuring each instrument retains its tonal character while enjoying the full depth of the effect. Whether you’re chasing vintage shimmer or experimental soundscapes, the BF-3 adapts seamlessly to your setup.

  • Guitar and Bass inputs for optimized frequency response

  • Produces both classic and modern flanger textures

  • Stereo output for wide, spacious effects

Creative Stereo Modulation

The BF-3 introduces Ultra and Gate/Pan modes, expanding its tonal palette far beyond traditional flangers.

  • Ultra Mode: Creates powerful, high-intensity flanging with deep resonance.

  • Gate/Pan Mode: Delivers rhythmic, percussive effects and swirling stereo motion, perfect for creating immersive live soundscapes.

The result is a versatile modulation pedal that brings both vintage warmth and modern flexibility to your board.

Rugged BOSS Design

Built with the same bulletproof construction as every BOSS compact pedal, the BF-3 is designed for years of reliable use on stage and in the studio. Its quiet operation, buffered bypass, and intuitive control layout make it easy to dial in your sound—whether you’re chasing subtle shimmer or full-on jet-engine swirl.
