This pedal can go from overdrive to distortion, but it doesn't sound like metal; instead, it produces a Guns N' Roses or Aerosmith-style distortion sound. It's less quirky than a Riot or BEOD and pairs well with Fender-style clean amps. If you're hesitating between the final version with five knobs and this one, the four-knob version is definitely better.
