BF-2 Flanger

The Boss BF-2 Flanger is an analog flanger pedal that was produced from 1980 to 2001. Using a bucket brigade device (BBD) circuit, it delivers warm, musical modulation ranging from subtle chorus-like movement to dramatic jet-plane flanging. Its four controls—Manual, Depth, Rate, and Resonance—provide precise adjustment of the delay time, modulation intensity, sweep speed, and feedback, allowing a wide variety of classic flanger sounds. Renowned for its rugged Boss construction and reliable performance, the BF-2 remains one of the most recognizable and sought-after vintage analog flangers alongside the A/DA Flanger and the Electro-Harmonix Electric Mistress.
