The BOSS DS-1 Distortion is a true icon in the world of guitar effects. Introduced in 1978, BOSSs first distortion pedal defined a bold new sound, delivering a hard-edged attack and smooth sustain thats 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.Genre-Defining DistortionBefore the DS-1, most distortion pedals produced harsh, buzzy tones and muddy sound at high-gain settings. In 1978, BOSS engineers changed all that by developing a unique distortion circuit for the DS-1 that produces tight, hard-edged gain with rich harmonics while retaining the unique characteristics of different guitars and playing techniques. Hard rock, metal, and punk styles began to flourish in the 70s and 80s, and the DS-1s tone had a defining influence on these genres. That trend has endured through multiple generations, and players around the world continue to seek out the classic DS-1 sound.Gain from Mild to HeavyFrom its modest three-knob interface, many different sound colors can be coaxed from the DS-1. Its pioneering two-stage circuit incorporates both transistor and op-amp gain stages. This approach is critical to the DS-1s characteristic low-frequency fullness, which is loved by guitarists that play heavy music genres.Powerful Tone ShapingUnlike typical tone controls that only cut highs, the DS-1s tone circuit features an innovative design that offers far more range. Turning the knob clockwise increases highs and decreases lows, while going counter-clockwise has the opposite effect.
