Boss BF-2 - Vintage 1982 Black Label Flanger Pedal - Pre-Loved

This is a vintage pedal in average condition. Externally, it looks like its earned all of its scrapes, scratches and knocks over 40-odd years, but it still sounds great and works perfectly. 

This pedal is now considered a classic machine that has been discontinued and is capable of a wide variety of sound making, including intense and acrid jet sounds, chorus-like sounds, and vibrato-like sounds.
Its deep swell and smooth curves have an appeal that is still applicable to today's music, long after its development.
