Boss BF-2 Flanger. "The purple one."
The Boss BF-2 Flanger is no longer being made.
- Thermionic Studios has one (1) Boss BF-2 available for rental.
Controls
- Knob 1 - "Manual":
- Knob 2 - "Depth":
- Knob 3 - "Rate":
- Knob 4 - "Res": (Resonance)
- Footswitch 1 - "On/Off": This switch toggle the pedal effect off and on.
Bypass:Buffered/True
Like all Boss pedals, the BF-2 Flanger has a buffered bypass.
General Information
Pedal Manual
Phase Inversion: Unknown
This is a rather unusual schematic. Instead of putting the correct symbol in the schematic for the modulation ICs, they've just drawn actual ICs. We also can't tell the electrical polarity of the ICs that are opamps because "2" and "3", and "6" and "5" are not indicative. We'll have to go looking for the opamps to better understand. To the best of our knowledge, most, but not all opamps have negative on pins 2 and 6, and positive on 3, and 5, but not always. As with other pedals, we'll have to put this on an oscilloscope to make sure whether it inverts phase or not.

On the schematic there are additional opamps and transistors shown, but they're controlling the modulation and power of the oscillator IC (seen very center). Those remaining transistors and opamps aren't touching the sound signal directly, and so do not affect the signal phase in the pedal.
