From Boss:

“The Classic BOSS Distortion, Enhanced with Waza Craftsmanship

Introduced in 1978 among the earliest models in the BOSS compact series, the orange DS-1 redefined the sound of distortion and remains as influential today as ever. Its hard-edged attack and smooth sustain have made it the best-selling compact effect to date, and its distinctive tone is behind the signature sounds of a long list of rock and alternative icons. With the DS-1W, this legendary stomp joins other BOSS classics in the Waza Craft series, fusing the look and character of the original with a newly revised discrete all-analog circuit for expanded range and versatility.”

Brand new.
