The Boss BF-3 gives the classic flanger effect of guitarists and bassists in full stereo sound. Thanks to the two new modes, Ultra and Gate/Pan, a stereo flanger effect is played with depth, which makes the sounds around you and the Silcer effect seem to move.
Tap-Tempo function: When you print the pedal at the tempo of the music, your pedal is tuned to the music. This feature is called the Tap-Tempo function
Momentary mode: The momentary mode ensures that the flanger effect starts right away.
