The Boss DS-1 is one of the classic effects pedals every guitarist should own, the DS-1 Distortion pedal provides a harder distortion effect for guitar and keyboard sounds. Instead of toneless, fuzzy distortion, the DS-1 faithfully reproduces all the subtle nuances of playing dynamics-at any volume.
The BOSS Distortion DS-1 is an up-to-date unit, and is provided with control knobs for Distortion, Level and Tone. It can produce a range of distortion tones from mellow to intense. The more you turn the distortion knob clockwise, the thicker the sound and the longer the sustain time gets.
