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.

- Momentary mode turns flanging on instantly 
- Tap tempo adjustable via pedal
