Building on the 20-year legacy of the famous Boss BF-2, the BF-3 Flanger pedal gives guitarists and bassists an updated version of the classic Boss flanger with the thickest stereo flanging sounds ever. Two 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.  

Features:

- Boss' best flanging effects in a compact pedal - Ultra and Gate/Pan modes for ultra-fat flanging with very low noise - Momentary mode turns flanging on instantly - Tap tempo adjustable via pedal - Independent Guitar and Bass inputs and stereo outputs - Boss 5-year warranty

Uses 9-volt battery or PSA-120 adapter (not included)
