Boss SG-1 Slow Gear

The Boss SG-1 Slow Gear is one of the rarest boss pedals and was produced in Japan by Boss in the early '80s. The effect replicates the sound of a guitarist rolling their volume knob to give a somewhat tremolo-like sound but with a dynamic all its own. Slow Gears are exceptionally rare when compared to other Boss pedals making them one of the most valuable to vintage pedal collectors.
