Boss BF-3 Product Overview by GAK

The BF-3 flanger pedal is the evolution of Boss' vintage BF-2 pedal.

The pedal features a mesmerising stereo flange effect alongside two new modes (ultra and Gate/Pan) which create a flange sound with unrivalled depth. There's also a slicer that creates a swirling flanger sound.

Turn on the hold-to-activate tap tempo to help you keep in time.

Boss Product Overview

The BOSS BF-3 flanger pedal is the out of this world evolution of the legendary BF-2. With thick, syrupy stereo flange effects, the BF-2 is a tough and affordable addition to any musician's pedal board. It's versatile too- BOSS have given us separate inputs for guitar and bass. You can keep in time with hold-to-activate tap tempo while painting psychedelic soundscapes with the unique slicer effects and classic stereo flange goodness.

    Incredible pedal, produces amazing sounds. From massive fuzz chords to gentle picking this pedal transforms your sound beautifully.

    The BF-3 can't do one or two of the tricks an original BF-2 could, but offers some great new modes. Great flanging sounds and that rock solid Boss enclosure.
