MPN #BF-3
Thick stereo flanging with Ultra and Gate/Pan modes, tap tempo, independent Guitar/Bass inputs, stereo outputs, compact design, modern flanger evolution.
The BOSS BF-3 Flanger builds on the iconic legacy of the BF-2, delivering the thickest stereo flanging sounds ever crafted in a compact pedal. Designed for both guitarists and bassists, the BF-3 introduces two new modes-Ultra and Gate/Pan-that expand its sonic range with swirling, slicer-like effects and dramatic stereo movement. The Momentary Mode enables instant flanging with the tap of a foot, while Tap Tempo ensures perfect synchronization with your performance.
Equipped with independent Guitar In and Bass In jacks, the BF-3 seamlessly adapts to any instrument, offering rich, textured modulation that cuts through the mix. Manual, Depth, Rate, and Resonance (RES) knobs provide precise control over your flanging effect, while stereo outputs deliver immersive spatial sound. Powered by a 9V battery or optional PSA-series AC adaptor, the BF-3 is built for reliability and ease of use, making it an essential tool for modern musicians seeking lush, expansive modulation.
