The BOSS DS 1 is already a classic among distortion pedals. Compared to the legendary overdrive pedals from BOSS, it provides considerably rougher and more aggressive distortion, which is clearly oriented towards the stack sound of British amps and further away from the rather toneless fuzz sound of older distortions. DS1 is certainly a good shout for fans of a harder style. With level, distortion and tone controls one can naturally create tamer sounds. Regarding the stability and reliability of BOSS effects you don't need to say much more anyway.
