Not to be confused with the 40th Anniversary DS-1-4A model, the DS-1 BK was a very limited run of only 3000 DS-1's sold by Guitar Center in 2016. These feature a true inverse color scheme with orange text (unlike the 4a which has gold text) and a black thumb screw.
This pedal is lightly used and we'll ship it to ya safely and swiftly! Give us a shout at the shop with any questions you may have.
