Boss BF-3 Flanger


  • Manual
    sets the position of the effect when the LFO is in the center position or controls the effect when the LFO is switched off
  • Depth
    controls the depth/amplitude of the modulation (the size of the range in which the effect sweeps).
  • Rate
    controls the speed/rate of the LFO wave that controls the effect
  • Res
    sets the amount of effected signal fed back into the effect (for a stronger effect)
  • Mode
    switches between 4 modes: Ultra, Standard, Gate/Pan, Momentary



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 with very low noise
  • Momentary mode turns flanging on instantly
  • Tap tempo adjustable via pedal
  • Independent Guitar and Bass inputs and stereo outputs
