One of the rarest of them all, the BOSS SP-1 Spectrum is a single-band parametric EQ pedal, well known for its ability to boost selected frequencies and help instruments cut through a mix. The Spectrum control sweeps the boosted frequency range from 500Hz to 5kHz, while the Balance knob controls the overall level. A distinctive and versatile vintage pedal for shaping tone and adding presence. Long discontinued and difficult to obtain. One for the collectors and players.
Made in Japan.
Missing two x screws however there has been an additional screw made in the baseplate. Functioning perfectly otherwise. (DC 9v centre negative ONLY - not PSA).
