Up for sale, a circa 1990 Boss BF-2B Bass Flanger pedal in excellent condition and in perfect working order. This uncommon green label Boss offering delivers a wide range of flanging effects, from mild chorus and vibrato to swooping airplane whooses and massive rolls of thunder, calibrated specifically for bass frequencies. The streamlined controls include Manual, Depth, Rate, and Resonance knobs.

There is only very light wear on the enclosure edges, with original knobs intact and the "Made in Taiwan" green foil label present on the bottom.
