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.
