Used Boss DS-1 40th Anniversary

Very good condition, with original box and manual.  From Boss:

Sporting the same legendary circuit that's been electrifying rock rigs for four decades in a limited-release chassis, the Boss DS-1-4A Distortion 40th Anniversary Edition commemorates a pedalboard staple. The same three controls for distortion, level, and tone afford the full landscape of light snap to full-on saturated snarl in a black-and-gold chassis available only in a limited run.
