1970’s Boss BF-1 Flanger

A rare first-series offering from Boss, the BF-1 Flanger is an early analog modulation gem with deep, liquid swirl and a warm, musical sweep. With controls for Manual, Depth, Rate, and Resonance, it offers a wide range of textures—from subtle movement to full-blown jet-plane whoosh. Built into a rugged silver enclosure, this is a collector-worthy piece that still holds its own on any modern board.
