Up for sale, a late 1970s Multivox Big Jam Biphase-9 pedal in exceptional condition and in perfect working order. Produced by Firstman Japan during the late ‘70s and early ‘80s, the Biphase-9 delivers a lush, warm flanger effect; variable from a subtle shimmer to warped, watery weirdness.
Controls include sliders for Width, Rate, and Resonance. Resonance dictates how much of the wet signal is fed back into the unit and doubled (hence the Biphase moniker), significantly intensifying the overall effect. This unit is in fantastic shape; with original slider tips, clean graphics, and cosmetic wear on the slender red enclosure limited to a handful of tiny nicks.
