The BF-3 from Boss is a compact pedal that creates thick stereo flanging and slicing effects for guitars and basses. It features a "momentary" mode where the effect is only on when the pedal is held down. It's a powerful tool for varying the tone of your instrument, and discovering creative new means of expression.

The BF-3 runs on a standard 9 volt battery, or on an optional PSA-series power adapter. It features two 1/4" instrument inputs, one optimized for guitars and the other optimized for bass guitars. There are two 1/4" outputs that enable stereo operation.
