An absolute classic modulation pedal — the BOSS BF-2 Flanger has been swirling, whooshing, and jet-planing its way across pedalboards since the early ’80s. From subtle chorus-like shimmer to full-on, sweeping flanger chaos, this purple box delivers unmistakable vintage character.
 
Simple to dial in with Manual, Depth, Rate, and Resonance controls, it covers everything from gentle movement to wild modulation. Built like a tank, as every BOSS pedal is, and still going strong decades later.
 
This one’s in great working order with a few cosmetic marks as expected for its age — a proper workhorse pedal that’s stood the test of time.
