The Benchmark in Guitar Distortion
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.
