Building on the 20-year legacy of the famous BOSS BF-2, the new BF-3 flanger pedal gives guitarists and bassists an updated version of the classic BOSS flanger with the thickest stereo flanging sounds ever. Two new modes (Ultra and Gate/Pan) create stereo flanging with incredible depth--even Slicer-type effects and sounds that seem to "swirl" around the listener. An instant classic. BOSS' best flanging effects in a compact pedal. New Ultra and Gate/Pan modes for ultra-fat flanging and futuristic slicer-type sounds, respectively. Momentary mode turns flanging on instantly. Tap tempo adjustable via pedal. Independent Guitar and Bass inputs and stereo outputs. BOSS five-year warranty.
