The BOSS BF-3 Flanger is a versatile, modern take on the classic BOSS flanger, delivering enhanced stereo effects and dedicated modes for both guitar and bass. First introduced in 2001, the BF-3 builds on the legacy of the BF-2, adding Ultra and Gate/Pan modes for even deeper, more dynamic modulation. With controls for Manual, Depth, Rate, and Resonance, players can shape their flanging tones from subtle movement to intense jet-plane sweeps. The BF-3 also features a tap tempo function for real-time speed control, making it a powerful and expressive modulation tool.
