Dirt pedals are usually labeled either Distortion or Overdrive. The OS-2 is both. With the color knob in the min position, the OS-2 produces pure overdrive. Turn it up and the overdrive will be gradually mixed with distortion until the overdrive tones are completely gone in the max position. The OS-2 provides maximum versatility and it can be used for every type of music.
The OS-2 has been around for a long time but have not been through any known circuit changes so far.
