BOSS BF-2 Flanger (1990 - Early Taiwan / Green Label / ACA Spec)

Overview The BOSS BF-2 Flanger is a legendary analog modulation stompbox, famous for delivering everything from subtle chorus-like shimmer and rich swirl to dramatic jet-plane swooshes and metallic hollow tones. Produced in 1990, this unit hails from the desirable early Made in Taiwan transition era, featuring the authentic Green Label, classic white-topped knobs, and the vintage-correct ACA power specification. Powered by classic BBD analog circuitry, it delivers a musical warmth, three-dimensional depth, and punchy presence that digital recreations cannot duplicate. It remains an enduring classic relied upon by David Gilmour, The Cure, and countless post-punk and rock icons.

⚠️ 【POWER SUPPLY SPECIFICATION NOTE】 This 1990 unit features the vintage BOSS ACA specification. It operates at optimal voltage using a BOSS ACA adapter or a standard 9V battery. If powered alone by a modern 9V PSA power supply, the LED may appear dim and headroom may be limited (unless daisy-chained with other standard 9V pedals to share a common ground).
