The DS-1 Distortion is a true icon in the world of guitar effects. Introduced in 1978, BOSS’s first distortion pedal defined a bold new sound, delivering hard-edged attack and smooth sustain that’s been a staple of players for generations. The DS-1 is the top-selling BOSS compact pedal ever, and its original, unchanged design continues to inspire the creation of great music everywhere. The classic DS-1 tone is behind the signature sounds of numerous rock legends, and is ready to fuel your own signature sound today. Classic tones for all types of music. Hard-edged attack remains clear even at maximum distortion settings, ideal for heavy rhythms and cutting solos. Works great as a booster at low distortion settings. Unique tone control offers a wide range of sound shaping. Doesn’t mask the unique sound characteristics of different guitars, pickups, and styles. Turning down the guitar’s volume cleans up the tone without introducing muddiness. BOSS five-year warranty.
