Up for sale, a 1981 Boss BF-2 Flanger in excellent condition and in perfect working order. Introduced in 1980, this is an early production, black label, made in Japan BF-2. Flanging effects ranging from mild chorus and vibrato to swooping airplane whooshes can be achieved with the Manual, Depth, Rate and Resonance knobs, allowing the user to easily dial-in the desired parameters.

Cosmetically, there is only minor wear on the enclosure edges. The "Made in Japan" black foil label is intact on the back, the serial number sticker is present in the battery compartment (dating production to October, 1981), and the original quartet of black knobs are in great shape.
